Nistune Forums

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

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

Between knock sensor signal wire and ground.

Thanks for the expedient reply Matt.

Its all sorted.

much appreciated.

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...

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...

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...

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...

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 ...

I'll try and find the log i was using and mark the time stamps.. Sorry for the tardy response, i didnt receive a notification of a response for some reason.

Hi Matt,

The innovate LM-2 aren't displaying correctly. is it a rounding error?
bit weird, only noticed whilst looking for another problem. both taken from same log 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 ...

Thanks. Makes it impossible to setup the app off line.

will the option stick or reset like the stream mode logging one?

Hi Matt, I'm working on an Alcohol engine again and it's been a while and several upgrades later it apppears the Lambda "tick box" is missing from the file, configuration. Also wideband outline for settings box, in menu also appears to be blurred with 'consult settings' border lines but I ...

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.
