My Ecu Program should be done in a week or two, and fine fuel mapping is done via an emanage. All Timing is done with the ECU from Technosquare. So for all of you out there that want to go this route I am sure technosquare will be able to help out. Oh and the turn around is like 2 days from Michigan to California and back. And I am not planning on switching up to a Z32 MAF, after this I am done with modinfying this car.

need:

555cc injectors for this program. I am not using a Z32 right now, I am using the emanage boost sensor to compensate for this.

 

Last I heard TS could not adjust the ECU for the z32 MAF and larger injectors, which is odd because that is one of the easier things to do. Setting timing maps is much harder. So is the TS ECU just changing timing and AF?

Do you think it is worth it to have the ECU reprogramed just for the timing and AF if you already have e-manage? IMO it would not be.

 

I am not sure if they can tune for z32, but I am sure they are tuning for the 550's. Reason I still need Emanage is because I am in Michigan and for fine tuning to A/F ratio the emanage makes it much easier because sending the ecu to California all the time sux.

 

Mikes point is that you can do the exact same thing with emanage as you are attempting to do with TS ECU.

Why spend the money on both things when the emanage can replace the TS ecu entirely...? There's really no need for the TS ECU if you already have the ability to do the same things with emanage. You are spending money to do the same thing twice.

Emanage can adjust: timing maps, fuel maps, injector size, MAF size. All with the ability to fine tune.

TS ecu can adjust: timing maps, fuel maps, injector size (maybe), MAF size (possibly). With no ability to fine tune it.

Only reason I can think of to get a TS ECU is for the raised rev limiter. Are you getting a raised rev limiter? Supposedly they can only raise the rev limiter on auto ecus.

 

and even with that, there are a couple versions of the ecu and they can only get one of those versions to work.

 

I believe you may be wrong. I have two very good tuners that refuse to tell me that the emanage will successfully pull timing and that the ecu won't add it back in later thereby defeating the emanage.

They did both state that the emanage would pull out the timing but I would have to disconnect the ecu every week or so to erase the long term memory that is in the OBD 2 ECU.

SO I already had the Emanage and planned on not having to do an ECU reflash. But now that I have run into the timing issue, I went ahead and got the T/S ECU.

However since the car is being tuned in Michigan and Technosquare is in CAlifornia it makes it very hard to get all the tuning right first shot so the emanage is being used to "clean" things up as far as fuel goes. And then the ECU is sent back for adjustment.

Why not JWT, because all of the horror stories of turn around time and things not being right I have read about here made me go a different route. So far so good T/S is very good an turn around is good.

So Yes, Mike is right if you already have the emanage and you could get by with out the Reflash if your willing to take the risk of your cars tune going to **** all of a sudden under boost and the ecu adding the timing you pulled back in and therefore bye bye motor- but thats entirely up to you I guess, I'd rather trust my tuner than a "hey this may work or in theory." Past practice seems safer to me.

Not meaning to flame others (this forum has been great and very helpful), I am not a tuner and every time I try to get advice on specifics I get "read the stickies" or no reply. So I am forced to trust others outside the maxima.org community.

 

Ummm guy, I and many other people are running Emanage and pulling timing with it. I think myself and others told you this in another thread too, unless it wasn't you. We told someone within like the past 3 days. I think these tuners are a little confused, or you are confusing what they are telling you. There are thousands of people across this country using emanage on OBD-II cars.

 

Or if you are still unconvinced, why not skip the TS and get J&S safeguard instead. Far more capable, dynamic per cylinder timing control rather than just some static rom tune.

 

Yes, that was me, and I could be wrong. However, I just don't understand why pfi and godspeed are both telling me this, they are both very good at what they do. Pfi explained that the long term memory would recognize that the ecu is being tricked and then add timing back in. On a separate note if it would do this on timing what would keep it from doing this for fuel?

Like I said I am not a Tuner, I am a mechanic, and would rather let someone else tune it.

If these tuners are confused I would appreciate someone that understands tuning give them a call (PFI-poc Bill 1-970-377-2216) and (Godspeed-poc Dan 1-248-305-8140) and then post how I am misunderstanding what they are saying. They both concurred on the emanage being unable to do timing and I know dan is very good with emanage among other piggybacks and stand alones.

Also What is the wiring diagram for the timing harness, I have hals from his site- my understanding is that it is spliced in just like the rest of the emanage-right? Where to put the diodes? Dan claims the coil problem was software related and has been fixed, which in my mind means that diodes would no longer be needed-right?

 

My point was that using both a TS ECU and e-manage is not the most simple way to go about your tuning. If TS can indeed tune for a Z32 MAF, larger injectors, timing, and AF then just use that along with an SAFC for fine tuning. Unless data logging is a main reason why your using the e-manage. IMO, the most simple set up possible that still gets results is the best way to go.

How much boost are you planning on running? Your SC right? I would not even worry about timing unless your well into the 300 whp range. Just make sure your using the highest octane available. You mention that you are not going to be using a Z32 MAF, so you won't be making much more than 300whp anyhow.

As far as e-manage and timing, There certainly has been maxima guys who have retarded timing successfully via e-manage. I don't see how the ECU is going to revert back to stock timing. E-manage is just a piggy back. It intercepts a signal, changes it and sends it to the ECU. How would the ECU ever know it is there, it doesn't have some sort of fancy artificial intelligence. It just reads voltage levels and makes it's programed adjustments.

 

Not sure about how the ecu knows it is being tricked? All I know is what I learn from those that are more experienced than I am.

I am running 11-12psi intercooled S/C. I put down 309 @5500rpm when the car started to detonate on 94 octane. So My tuner stopped and I went for the Technosquare because the Emanage was not a permanate fix for the timing issue due to Technosqaure stating that eventually the ECU will recognize the Emanage is pulling timing and will then circumvent the Emanage putting the timing back in -ie adding on top of the 5 or so degrees pulled to put the car back to say 34 degrees advanced instead of the say 29 advance.

Since Dan was not able to pull the timing and do a full throttle run to redline-becasue of detenation with the (i believe 34 degrees advance) timing like it was he had technosqaure pull 15 degrees across the whole map (which is rediculus even he stated that) (I was getting detenation on the street at just half throttle-no boost). therefore last week he was able to do a full run and it only put down 301hp @6500 rpm. So we sent the Ecu back to add timing back in I expect 350 minimum and would like more (dan expected 370+ based on the first pull of 309). And the A32 was close to maxing out the first 309hp run which was like 4.6volt. I don't care about switching to the Z32 maf right now and am using the emanage psi sensor to compensate.

I do need to use the emanage for my set-up, I was originally hoping to only have to use my stock ECU and the emanage. However it hasn't worked out like that, so the emanage is paid for so why not use it?

 

dude you'll be in good hands. dan is a good tuner. and if he wasnt people wouldnt be driving in from all over to get their cars tuned by him.

 

Wait was it technosquare that told you that the ECU will "override" the emanage or PFI and Godspeed. First you said PFI/Godspeed and now you said technosquare. Do you have MEVI? It seems like you are in this to get as much power as you can (as you stated you are shooting for 350) why are you selling your car short by going with TS ecu rather than JWT, for the extended redline I mean (other than the fact that no one wants to wait 12 weeks for a JWT ECU). You'd probably gain 30whp just by going from 6500-7200 redline.

Not sure if you saw my other post above, but you might want to consider J&S Safeguard rather than the TS/Emanage setup. J&S is FAR superior for detonation prevention, and about the same price.

 

It was all three of them they all concurred, godspeed and technosqaure spoke and came to the conclusion. I then called PFI to see what they thought for my own peace of mind.

I don't have a MEVI.

And based on all the negative things I've read about JWT I didn't want to go down that road. such as: long wait, check engine lights, bad customer service, and most of all a generic tune for all cars.

 

....and I didn't either. I'm not boosted but I didn't want to deal with JWT at all. Just keep working with TS so that they can figure things out and then more people will be able to go to them. As it is, JWT gives everyone the shaft with making them wait and with their bad customer service. They're jerks.

Just keep researching all your options and good luck.

 

Thank you for your vote of confidence. I do really trust Dan he does a really good job and does it 100%. I am really surprised at how he really will got the extra mile, as my car has been for a 2+ weeks for just a tune. Good thing is is that I know it will be done right the first time and If I do run into problems he will be willing to help out. His customer service is great and technosquare seems really willing to get my ECU done right, that and they are really quick about it! Unlike JWT-so I hear.

 

Yes it's definately true that JWT is not very customer-friendly and I understand your reluctance to give them your money. However being as you are planning on controlling air and fuel and timing with the emanage, ultimately, once you have it in your posession, the JWT would make your car both faster and more powerful.

It's great that TS is willing "custom tune" your ecu, but the fact remains that they a) never done what you are requesting before, it will be their first time (unless they have done boosted tunes since I last talked to them) and b) they don't have your car in their posession so whatever "tune" they do is still going to be an estimate, they simply can't do it perfectly without your car on a dyno (which will be solved by Dan apparently).

It really makes no real difference to me obviously, it's your money, but I give the same advice to everyone on here, and I'm giving you the best and most honest advice I can think of. I'm just confused as to why you are going the extra mile in some aspects (having Dan tune your car, buying not one but two things to control timing to ensure that you don't have a problem and yet not using the best timing control device out there (J&S) which is worlds better than anything else you have mentioned using, and not any more expensive either, etc) and yet cutting corners on others (using MAP sensor rather than having an airflow metered system, map sensor won't compensate as well for the drastic atmospheric changes we have here in Michigan) etc. It's just confusing to me. I hope the whole process works out for you, and I know (well I've heard) that Dan is a good tuner so I'm sure things will work out in that respect.

Where in michigan are you living? I see your profile says Indiana still. I'm in Kalamazoo and it'd be cool to get together some time maybe at the track or something. Could have Mike and brian come, and huyqvu too and we'd have like 5 boosted VQs in one place in Michigan, that's unheard of haha.

 

I would love to get together some time.

I won't be using the emanage for timing, once Technosquare gets the timing squared away that part will be done, and yes it would be easier to have the car in california, but that is not possible for me. And Technosquare does alot of the ecus for the 350z's that are boosted right now.

We will be using the emanage to clean up the fuel maps though. but Dan has done wonders with car already and i expect the next tune will be really good.

i do still live in Indiana, I just went to Dan because I've heard how good he is, and he just did a great job tuning two of friends turbo cars one was an integra 260+ hp and an h22 prelude 300hp. they don't avertise other than through their customers, They're very good and the Customer Service is better than anywhere I've ever been, especially when it comes to Car work, and when you have it extremely modified, they bend over backwards to make things right, and do it safe! G

Godspeed has done some great work for me so far I really reccommend you guys check them out!

 

this is crazy....one guy wanted a custom TS ecu tune back in the day...and ended up getting 3-4 and even 5 degrees more across the board then he submitted to them...long story short...his car detonated like crazy and it took him several times of sending it back and forth to get it to work and having the exact timing map he wanted....and TS has not figured out the rev limiter for the 5spds...and it seems of no importance to them when I was having mine done...lastly, the emanage should have absolutely no problem pulling timing (many, many people do it all the time)....or the customer service line over at Greddy would be ringing off the hook with customers complaining that it was not explained that ecu's will add the timing back after a while in the manual/disclaimer...in other words, the ecu has no means to know if it's being fooled or not which is why the J&S safeguard works beautifully as well, it intercepts signals to pull timing--nothing more...

TS will never be able to give the exact timing that is optimal for you car...whereas with emanage you can get on the dyno and keep bumping it up until it detonates, then back it down slightly (and choose a hot day just to be on the safe-side)....with emanage you can even make different profiles for when the weather is especially cold, you can implement that map set...so you see as one guy did...you won't circumvent the issue of constantly sending the ecu back and forth...cause you still will to keep getting the timing map to be changed...

I would certainly understand this setup if you were trying to dump the emanage in total and go with an entirely ecu controlled environment with an exact tune of the TS ecu...

 

I would like to come too Neal. I know that I have been working on Sundays and thats when yall usually go, but I should be changing jobs fairly soon.

Brad is close to y'all too.

 

haha miine car isnt boosted yet, but almost there. still need injectors, fuel pump, fpr, fuel pressure gauge, ic and piping, manifold, and boost a spark. other than that everything is sitting in the back of the shop on a dusty shelf waiting to be installed. most likely andy from autowerks is tuning mine, but dan is always there when andy is tuning. so 2 great heads working together.

 

You can come but brad is not allowed since he doesn't have a VQ hahaha just kidding brad

 

any update on this?
