Re: Stalling under deceleration

Often the TP Max is too high, the fuel map under light load is too high, the Decel spark is not high enough or DFCO needs to be a little wider.

The problem can be worse with a BOV, MAF, Injector upgrades and FPCM elimination

Re: Flat shift

if the engagement RPM could be modified from 1200 then a momentary double pole trigger switch could be used along with launch control parameters.

fuel cut - fuel recover type VLT non FP

Hi Matt, Today I tuned dug out one of our trusty VL circuit cars running on old firmware to convert to E85 but found that the "fuel cut rpm" "fuel recover rpm" parameter in nistune version 1.2.68 are now missing. I'm guessing the address file is the issue. The engine has an issue when the throttle i...

Re: S15 SR20DET JDM

yeah , I read the doco, it was for nonFP code but its still fairly relevant. knock analysis, knock map "K'', and knock retard all modified. issue sorted. The over fueling I'm fairly sure is a Z32MAF pegging at 5.11v at only 300hp at treads. we originally though misfire caused from over fuelling, but...

Re: S15 SR20DET JDM

Yes some of the maps were changed in troubleshooting. If you grab a stock 91f0f .. same happens. The mechanic was insistent on tps issue but with dtc on knock being one problem, i just can't understand why the second the throttle movement takes engine outside of closed loop areas that it drops afr d...

S15 SR20DET JDM

Hi, Calling for SR Expertise on this one. I have an SR20DET with a preFP tune in it that has Z32MAF, 740cc injectors (possible upto 1000 I just found out). Issue is, if run up at cruise, light throttle and very slow TPS movement, AFR's a little on lean side 17's. as soon as you move throttle quickly...

Re: RB25DET MAF Delete

MAF delete is the wrong terminology.. not deleting the MAF. it will simply be replaced with a better one and installed in a new location such as your 3.5" interceptor piping where it has the capability to read over 650HP. The wiring diagram is commonly available for both MAF's online or in one of th...

Nistune auto loading wrong address file

Hi Matt, today needed to view a Z32 ECU calibration. I opened nistune 1.2.68 it loaded the previosly used HCR32 FP address and rom file. I changed the bin to Z32 FP bin that I needed to view. nistune prompted that it need to load the correct address file to match the bin I was using. nistune opened ...

Re: Fuel map dynamic range

Sorry, I can no longer help at this point.

There is some really good information in the available Nistune manuals and guides. the issues in just the fuel map are huge.

I still can't believe your dyno tuned 420HP 1.5-2Bar boosted engine hasn't dumped its bottom end in the sump.
