I am not going to use that crap. I'll stick to the EU if I really wanted to have real control over the timing, etc.

If you really want to know what the definition of trouble is, go ahead and buy that thing.

 

any with a 3.5 4th gen ecu have a safc2 if so whats the settings?

 

up, down, up, down, left, right, left, right, select, start. that should give you an extra 9 lives.

 

I assume your talking about the Megasquirt? That's pretty pathetic. If hundreds (thousands?) of carburated V8 luvin' rednecks can figure out how to program a fuel injection and electronic ignition computer I for damn sure can.

lol, did somebody used to play contra back in the day?
so whats the difference between static maps on TS ecu's and jwt maps?

 

That's colorful lol.

 

I think megasquirt would be a step backwards. It's a primitive fuel injection system a la early 90's OBD-I. It's basically open loop all the time. While megasquirt is great for formerly carb'd engines, it wouldn't be so great for ours.

Can't use COP as well, have to use a distributor. That's definately a step backwards.

 

The only thing that is pathetic is that home made with Radio Shack parts thing you linked us to. So go ahead and put it on your car to prove to us how wonderful it is.


I personally would shell out the $3000+ for a Motec M600 setup before I wasted my time on something that I would use to put fuel injection on my lown mower.

 

how about UTEC?

 

Utec is really nice, but it would have to be programmed for our Crank/cam sensors(VQ30)

 

The UTEC also has a 350Z specific wiring harness.


For us the better option would probably be their DTEC-FC.

 

You do know that the "$3000+ Motec M600" is likely built with very similar components using the same or similar techniques and probably has little to no more features than the Megasquirt, right?

Also, the MS does support coil on plug but only certain types so far such as Ford's EDIS system among a few others.

SR20DEN, you seem very ignorant about the MS. You should look into it further before you so quickly attack it - if you are serious about tuning your VQ's fuel and/or timing.

allen

 

Some people use the Megasquirt and SMT together. I do not remember what apps used it.

 

I looked over the site and studied the schematics a little before I made the comments. The Motec M400, M600 and M800 are still the ONLY standalone ECUs that can control DBW, Nissan VTC AND BMW Vanos. And they don't need some external relay box to drive components.

And again, if the MS is so wonderful why don't you go ahead and buy one?

And while on that note, please make your own thread about it. One that I won't ***** up like you've done mine.

Thanks

 

Man, your bitter.

The external relay box is only needed on applications that didn't previously have fuel injection.

My intent was not to "***** up" your precious thread but to help you in your pursuit of timing and fuel control and hopefully encourage some useful conversation from some knowledgable members, yourself included. I understand you're not interested in the MS so I'll leave it alone. If/when I get my VQ running on the MS I'll post up the results.

i'm really looking forward to your results, allen

some of the best mods for the maxima came out because people said it won't work, or it won't fit, but others made it work (i.e. 00vi, 300zx brakes, 3.5L engine swap, 3.5L cams in 3.0, and the first turbo on a maxima.. if there's anybody here who still remembers those "good old days" when the only mods for maximas were the PR intake, cattman y-pipe, a few exhausts, and for the serious side the Vortech V1 SC -- Back in the day when Cheston still drove a 97 SC max

it's very easy to dismiss something, and say it's not going to work..

however..

SR20DEN is one of the more knowledgeable members of maxima.org, who has already proven he can do quite a lot with his maxima, check out his sig and look at his dynos. he always posts relevant information, and has been one of the people who made those previously unworkable mods possible. i'd take his advice, but that doesn't mean that the Megasquirt won't work. if you feel you can make it possible, try it out so we can know that it DEFINITELY does/doesn't work, for all i know it can be the next best fuel/ignition computer for anybody running a modified max, and you're the one who'll make it work.

i'm sure people said that the SMT will not work either, but ask Kevlo911 or JnotofThisWorld if it doesn't work for them (minus the bugs being worked out)

good luck, and happy tuning

 

I never said it wouldn't work. I stated my opinion that I think it's crap and that I won't attempt to use it. I have defended just about every piggyback or standalone box out on the market, when others were bashing them, except for this one. I am drawing the line at this thing and I want no part of it. But again, those of you that do should try one. No one said my opinions had to be the gold standard, often times people ignore my advice anyway.

The purpose of this thread was to show everyone how easy it really is to make ignition timing changes on these cars with a simple piggyback and some easy fuel system changes. I fail to see how on Earth this is more trouble than wiring up an entire standalone system.

 

"One that I won't ***** up like you've done mine."

I felt personally attacked there. Stephen Max, I trust you sent SR20DEN's warning via PM?


"I fail to see how on Earth this is more trouble than wiring up an entire standalone system."

I agree, your way is much more simple, I don't intend to bother you about it anymore. Sorry about that "bitter" comment, that was childish and I should have kept my mouth shut.

allen

 

He didn't call you a *****, per se. You did call him bitter. Maybe a subtle distinction, but I have to call the line somewhere.

No name calling please. Ad hominem attacks are inflammatory and can quickly lead to worthless flame-fests.

 

Might want to close this thread, we already got the info, pull maf V = added timing.

 

dont forget to either add bigger injectors or up the base fuel pressure.

 

Just curious when I looked at your link it says nothing about only 02-03....

 

No, it doesn't. But it's implied since 4th and 5th gens are not drive by wire. How can you modify the drive by wire on an ECU when there is none? How can you remove the speed limiter when there is none on a 4th gen SE?

The 6th gen has a totally different ECU than the 5.5gen. Therefore, the L-spec is only for 02-03.

 

Sucks because im ready for the L spec Flash.

 

BWAHAHAHAHA!!!!



I just noticed something reeeeeealy interesting. The A34 uses the SAME ECU connectors as the Z33. You guys can possibly use a 350Z ECU or the new UTEC standalone system from TurboXS .

I doubt all the pinouts are the same and I dont have time at the moment to study them, but.................



http://www.courtesyparts.com/Merchan...ct_Code=ASW180







When are you ***** going to bring me a A34 so I can do this stuff?




We can also add 05+ VQ35 Altimas to this list. 02-04 VQ35 Altimas still used the A33 conector.

It appears that all QR Altimas, and most everything else (Titan etc.), use the Z33 connector

 

Bump. For the search impaired.

 

Ok, not Maxima related, but Nissan related and timing advance related. My wife has an 05 3.5 Altima. I asked the dealer to advance the timing to 17, but was told that it would revert back to the stock 15. I have an 5.5 gen and did it to my Maxima without it going back to stock at 14. Just wondering if the explanation from the dealer was true or not, it is the same dealer that did my timing advance for free.

 

Anyone can help me? Thanks.

 

Ask the Altima forums. I doubt it reset the timing back to stock tho. IIRC, only the old ECUs do that(4th gen)

 

ok i kind of read quickly over this thread....say i bumped up to 94+ 300zx TT injectors and used a VAFC or SAFC to take away some fuel will it bump the timing like it does for the 02-03 guys or will the 4th gens ECU set it back to stock....after reading this thread it seemed most od it was for the 3.5 guys

 

You don't have to use larger injectors either. You can use a EB or EU to essentually do the same thing with the additional injection map. That will probably be one of my next projects after I put the OE injectors back in.

 

but u think the larger injector and afc will work on the 3.o though.....i have access to the 300zx tt injectors is y i ask

 

I'd like to bump this. This is a question I am wondering about myself. I'm a newb to this crap. When looking into larger injectors and a SAFC II system, does anything else need to be changed to get gains out of this upgrade?

 

well i have been educated since i posted...on 4th gens atleast i am sure 5ths are similar....run an adjustable fuel pressure regualator and an SAFC...take fuel out and it will advance timing

 

Leave the stock injectors, add fuel with an AFPR, then use the SAFC to tune back the fuel. You'll end up taking away MAF voltage thus bumping the timming slightly while gaining power.

 

how much timing do we get.....any definate numbers

 

Average gains?

What type of AFPR would be recommended?

 

sutter is getting a bunch of sr20 ones modified....AEM universal ....some have the Aermotive which is nice.....but a couple degrees of timing can make a big difference

 

Man, you guys in the states get all the good stuff. I probably won't be able to take advantage of the sr20 modified ones. Might have to settle for the AEM universal.

So injectors are not recommended? I read before 300zx TT injectors are a good upgrade as well.
