does not meet the load of TP z32 ECU RB25

Post by Bgtym »

in idle, rich. 12: 1
at medium load approximately correct.
levels boost, very lean 13-13.5 AFR
at the time as soon as the boost 0.1-0.2, TP runs on the values ​​of 80 wherein the mixture on the map 11, in fact 13-14.
load MAF does not match the load of TP
1) try to change the constant "K", No results.
2) try to rule curve "MAF", No results
3) tried to put the MAF Z32, No results
4) tried to put the stock MAF R33, No results

stock engine. 25det.
Stock injector 370
ECU Z32, stock map.
set R33 ECU everything works fine))

Which model R33? S1 or S2?

Load in attached base tune file (S1 RB25DET 370CC for Z32). If you have a Series 2 then change MAF to ER34 RB25 MAF in Operations > Resize MAF

After this let us know how it goes

If has the same problem, record a log file with RPM, AFM, TP, Inj time and AFRs so I can have a look.

This tune file is the standard start file we use on Z32 ECUs for RB25 so I know it works fine

we will try out your recommendations! and upload the log.
We have tried to put the maf z32. doing Operations> Resize maf z32. load calculates incorrect
we did not remove the stock knock sensor 1 and 2, it can be the cause?

That would not help. Stock knock sensors not compatible with Z32 ECUs

You have a TP of 80 at .1BAR?
What doe the MAF voltage show ?

the problem was the knock sensor,
removed the knock sensor! soldered 470Kom!
ignition time beginning to keep as recorded in the map.
before ignition time was -2 to 5.
stock knock sensor is very sensitive, switched to the map detonation.
prescribed MAF ER34. become better, but sometimes does not match, the mixture on low load +0.60 AFR at high load -0.50AFR.
constant "K" has been increased to 210 roughly corresponds to a mixture of high load.

Z32 ECU will not work with RB25 knock sensor. Different type of knock sensor. Needs to be disabled
