Re: Launch control

Hey! Is there any possibility to use launch control feature with P10 SR20DE ECU 70J10 at the moment?

J30_VE30DE_97E10_AT / J30_VE30DE_97E60_MT
So that MAF will work fine since I have the VQ map from these ECUs in the list already
OK, you should be right. Will give it a try.

Re: Low gear deceleration issue

Because it will be really hard to find/buy such MAF in Europe, I wanted to make sure I won't waste my money.
Will let you know in case such MAF does not work with the J30 VQ.

Re: Low gear deceleration issue

Matt,

This MAF:
http://www.ebay.com/itm/89-94-Nissan-Ma ... cd&vxp=mtr

Is it supported by nistune and included in the Change MAF drop-down menu?
Thanks

Re: Low gear deceleration issue

This seems to have the issue partially fixed.

Damn... So there is a MAF which is appropriate from my setup, but we don't know where exactly it comes from.
Why is this MAF in the drop-down menu then?

Re: Low gear deceleration issue

For the production period of Infinity J30 were used all together 3 different MAF's: 1/ 01.92 / 07.95 - 22680-30P00 2/ 07.95 / ... - 22680-31U00 3/ 22680-31U00 is also interchangeable with 22680-31U05 The first one says N62 on it?! I thought there is a separate listing for the N62 MAF under Z32 DETT:...

Re: Low gear deceleration issue

Your K constant has changed from 31206 to 21000. This is resulting from changing the MAF from the P10 SR20DE to P11 SR20DE MAF (should be about the same flow figures) and from 259CC to 370CC injectors (which is the main change) What I would suggest is a MAF upgrade like Z32 MAF which will bring K c...

Re: Low gear deceleration issue

I had this problem ever since I started dealing with nistune. I first purchased a type 3 board installed in a 83J ECU, which was using 64kb bin. Totally useless ECU, especially having the wrongly working VE table - as far as I know - an issue still on the list to be fixed by Matt. So 3 or 4 years no...

Re: Low gear deceleration issue

Compression test shows equal readings on all four cylinders (~11.75 with JWT S4 cams in), with differences not exceeding 0.25. The 370cc injectors are indeed OEM S14, tested, working great, removed from a half cut with less than 75k miles. Last September I used for a week a distributor from another ...

Re: Low gear deceleration issue

Nothing helps, the problem is still there. No matter what I do, no matter which table I play with, the problem is there. 1/ A new first load column was created in the fuel table with TP value matching the load during deceleration. No matter how I change the values in this column (no matter the AFR),...

Re: Low gear deceleration issue

How about my other question - is it normal that I see injection time values during deceleration? And besides the TTPmin, is there another table dealing with the injection time when TPS is ON?

Re: Low gear deceleration issue

What is your timing during the decell issue? Try adjusting it to see what happens. Do you have a lightened flywheel? The timing during the decell was really wrong. In the log file you can see it decreasing from about 15 degrees down to 4. Thanks! I got it fixed and below is how it looks now. What I...

Re: Low gear deceleration issue

Looking at the log file ending 33, focus on time from 00:00:20:327 to 00:00:30:202 You can see the TPS value during that time being 0.46 which is my idle TPS position. This is a 2nd gear deceleration. The ECU reacts as follows: 1/ at first there is an injection time of 0.75 leading to 20:1 AFR (shou...
