This is awesome, where was this like 5 years ago lol. Out of money now.

 

I sent the jwt ecu along with two others. I sent a 95 gle auto production date 11/94 and a 96 auto gle a well. They both have the jwt tune on them. I got the jwt ecu back the way it was originally. One Nistune ecu is as a back up just in case.

i just got an extra ecu so i can send mine off. awaiting the word

 

i actually have the money for this i might pick up one of these nistune boards.

 

Actually question. This might be helpful for people like myself that are on boost. Map sensors, 95s do not have stock map sensors, can that be added with Nistune aswell as the Wideband(quite frankly tuning off the maf is....well its not the best option.)

 

Updates?

 

To remove MAF and run MAP I would have to send it back after all the testing on the new boards is done.

As for now, I have only played with getting my idle fixed and some cold start issues. When in drive my idle always drops and the car feels like it will eventually stall. In neutral it stays steady at 750ish. So I bumped that up today to about 800ish while in drive and it feels great. I am also working on pulling back some fuel tonight at high rpm. My jwt tune runs at 10.9 at WOT. I will be working on getting that down to 11.5 before I take it in for tuning. Will know how cold start adjustments went in the morning.

There are so many options for tuning on this program. I have maybe 25 different table that I can play with. Plus all the consut data is streaming live when the program is running and you can log and trace it live.

is there an autotune if you have a wideband hookedup?

 

wow so map is a option

 

map is not an option with the current board, but it could become an option eventually

 

just got a email from nistune, please contact them and provide feedback

 

Got the ecu installed, car runs awesome.. Idles perfect, when I go into boost i'm around 11.8 cruising, right around 14.8-15.2on my AF. This set up is super easy to use..

 

What about timing

 

Can't remember what I set the timing as, but I can check my files tonight.. but the car run perfect, i'm loving this software though

 

so you tuned the a/f to based on maf voltage and rpm and the timing based on maf voltage tps

 

I thought the best/right way to tune was off of wideband....

 

You use maf and rpm as your axis of your tuning table, the AFR reading of the wideband is the product.

E.g: with maf voltage of 4.4V at 5000 rpm you add x% of fuel which results in an AFR of y.

VAFC uses throttle and rpm as the axis for its correction table.

On emanage I now use a map sensor and got rid of the maf.

The advantage of maf voltage over throttle is that it should be the same reading independent of the gear you're in.

 

what he said ^

 

so we send these guys our stock ECU and they load all the tunning info in the stock ECU making it a fully plug and play tunable stand alone?

Are a lot of tunners out there familiar with Nistune?

 

Yea, you send them your ecu, they install the type 4 board, load the ROM software, and send it back to you. I'm in New Mexico which doesn't have the greatest A32 support and I was able to find 2 tuners, I'm sure there are a couple tuners in your area.

 

Anybody know of a Nistune tuner in the Dallas area? I can't for the life of me find any

 

did a google search found these guys.

got a email from nistune so far everything is good to go, he said three people have the ecu, he's heard from two but waiting on the 3rd person. also that if launch control is added later on it would require a simple reflash and no extra hardware.

 

Thanks. I've never heard of backpage.com but I've done a bunch of Google searching over the past few weeks with no luck and called a bunch of shops most of which claim to have never heard of Nistune. So thanks for the link

I contacted him and he seems to be very thorough and really know his stuff. Hopefully I can get him to tune my car in the next week or two

 

Really? Awesome, Price. What is the price? I might buy one in the next 2 weeks.

 

Awesome man I hope everything works out man.

 

Wow, I've been away from the org for way too long. This is ****ing awesome.

 

Ill have to hit em up and c if they can do my 97 I talked to a tunin shop they said it was available for my car!! Def gonna look into it

 

Matt at nistune also said with enough demand he can look into the option of adding map

 

Well see.. I don't quite understand the advantages of a map sensor over a maf. But if it has an advantage and it's an easy conversion then I'd be all for it.

 

I talked to Matt about adding a MAP and he said that in order to do that it would require them to write a completely new ECU code. They are actually looking into a MAF insert. Here is the link he sent me.

Yes you have chris

 

Actually not quite long enough, it has suddenly start smelling like donkey d1ck.....

 

sorry

 

So how much will it be for us non field testers?

You should have brushed your teeth today.

 

Bought a '95 fed auto ECU for when the time comes. For $52 shipped

 

rather tune by map if possible for all that I'd just keep my z32 maf .. the point of tuning with map is so the car can run on the stock tune while in vac then make a crossover table which pulls timing and adds fuel based on boost/load instead of maf voltage. tuning by map will fix the 5th and 6th gear issues

 

I mean it can be done with a maf just requires more time and better understanding of what the ecu is looking for to make it do what you want it to do

 

I got mine for $20 at the local yard hehe



would a map be better on an NA car too?

 

I don't think it would be worth the hassle
