Nistune Forums

I have some probs connecting to my Acer notebook, running windows XP.

More testing, i saw that not only the injection ms goes skyrocket when i hit the throttle, but the Ing timing goes down! all this below 60º coolant

I have done this log

Hi! i have try do make the changes but it stayed the same! And something strange happened...after this adjustments.... at first, in cold start the engine starts fine at first, (in cold) if i try to rev the engine a bit it floods right away! and the engine shut down!, it starts fine again right away!...

Sure

Hello! Got my Nistune upgraded to the new firmware to use the FP upgrades, need to make some adjustments for my fuel setup (nismo 740) since old maps dont work anymore. Engine runs perfect AFR´s, the only issue is at warm start it injects too many fuel and is hard to start, in cold start is perfect!...

Some days ago my car have start to make +12 AFR on WOT it was running fine at 11.5 AFR in WOT and i log the nistune and the target AFR is around 11.3, also log some runs and all the other sensors( MAF etc) are fine. Injectors, fuel filter, fuel regulator is new. The fuel pump/controler and damper ar...

Any one whit the 300ZX TT Mines ecu bin file to share or trade?

I have

ash nismo 740 single
SZ 555 nismo single
SZ 740 Dual
and some more..

For safety take -1º degree for +1 pound of boost increase

Got it! tks matt

read old, but good Pete's post about rescaling. forum.nistune.com/viewtopic.php?f=12&t=763 Good info tks :) Good? no? :) BAD. you didnt understand that topic which I gave you. Why you should need so much points between 0 and 40? It could be in 4-5 columns because this is no load area. While 50-...

read old, but good Pete's post about rescaling. forum.nistune.com/viewtopic.php?f=12&t=763 Good info tks :) I did this changes in my map in the TP scales, is bit big scale because in my actual tune at only 16psi of boost i hit the 76 TP load... my turbos (GT2860RS) have a lot more to give. Also...

Yes this is what should be done next. Rescale the TP load scale for fuel and timing upto the maximum load read (see tuning guide for more info) Tks matt, i did this changes compared to the "stock" tune http://i1148.photobucket.com/albums/o576/lpskynet/loadsacleigfuel_zps5f53363f.png Also ...

I have done some logs/runs to tune the AFR´s , and i saw that i hit the max TP load in the fuel map and ignition (they are set to 64) http://i1148.photobucket.com/albums/o576/lpskynet/Loadsacle_zpsccd2da93.png should i rise up my scale to 76/80 like it show in the multiple display? http://i1148.phot...

Here are more infos: viewtopic.php?f=8&t=2472

Nice! i must try that tks mate

Yep thats it!

I Set the 'high gear coeff' parameter to 0 and now i get 12 air fuel ratio in high gears
