Nistune Forums

Upps, wrong pins mentioned earlyer. Signal to ptu are 1,2,3,11,12 and 13 and was the one we measured.... No my theori is that ecu might give to high voltage for ptu and that might be why ptus burns.... Tryed a oem ecu sortly and that one gave 0,1 V as manual says it should. So I will try moving Nist...

Have a z32 with vg30dett and nistune type 2. Been running good befor but after swaping tanother car we started burning ptu's. Both gen 1 and gen2. Sofar we have checked eartpoints and eartlines. Conections to ptu and switched to known good coils. What I have found are that ecu gives 0,5-0,6 V at idl...

Here is the map

Hope I hevent done anything totaly stupid....

Have a z32 -91 MT , with a AT ecu. Been running with Nistune a few years. Started up the car a few days ago and conected laptop with updated software to do a few changes before technikal checkup. After loading new rompack as prompted the car started to act strange. At idele Nistune show -1 deg, stro...

Most likely problem with maf.

Now have it runing quite god. Had help from one dyno mapping company. Now I just have to get powertrain to work propperly again so they can compleate, clutch stopped releasing..... Got out 463 Hp at rear tyres so I'm happy. Btw running on sard 850 injectors, so I can confirm that it is possible to u...

Well the afc have diffrent settings for diffrent maf's so there I think I'm right.

Tryied again with the 1/2 inj size and changed the inj latensy, seemd to help.
Rest of the problem can propebly be help by fine tuning the injektor k value then I hopp I'm home....

Realised what the add in afc does. Befor starting tha car maf gives app. 0.4 V. So 1,1 V+ 1,1 V is not 2,2. It will be 1,1-0,4+1,1-0,4=1,4.

Allways nice to know way I were confeused...

Tryied that but did't seem to work direktly. Will work more on this in a dyno and se if we can get it right. Just it would be nice to be one step ahead. What i also wounder abot is the afc. When I go in add mode it seems to not realy make 1+1=2... but this might not be the right place to ask about t...

I have installed double z32 (on a z32) maf's and a afc neo and would like to go with the average mode to make the maf's support higher power. Now I will get only half the air to the ecu ofcoures so, can I get this adjusted in the map? My idea were to half the injector size and get double feul per me...
