As per the email, if the upload/download does not work from NIStune, then neither will changing any of the values (if you used another tool to perform the upload/download to get the car running) I had all this working (and haven't changed the code since) when first releasing 0.910 and have returned ...

The Z31 VG30 would probably also have a higher HP reading than the R31 RB30 .... it has a larger diameter ... but that is not always a guarantee (given Q45 is larger diameter than Z32 but will top out sooner)

PL has indicated that he might be able to flow test some of these for us....

Okay this is really strange... and I did notice this also on RB30 when trying to use RB25 AFM on my R31 CA18 190HP to Z32 550HP K * 2.89 R32 300HP to Z32 550HP K * 1.83 SR20 290HP to Z32 550HP K * 1.89 .... now Z31 ??? HP to Z32 550HP K * 0.8463 The K is based from what bernard posted for his upgrad...

sorry only just saw this. our boards do CA18DE/DET so that will be fine

Ed runs a workshop... so would have been on dyno

Above updated

thanks for that with the latency issue... please see updated address files. values are different dependent on Z31 year. i've emailed an updated file http://forum.nistune.com/viewtopic.php?p=1773#1773 suspect will need to exchange your board. sounds like you might have 1987 firmware in there which re...

welll just found out that Z31 1984-85, 1986NA and 1986-1989 ECUs have different addresses for this.... 1984-1985 #Void blast-off time IGN_TIME,&H3F3E,1,1,1,1,Void blast-off time #Coefficient used to calculate true injector latency at current battery LATENCY_CHANGE,&H3F3D,1,1,1,1,Latency Chan...

Just to let people know that I'll be removing darkhalf@aanet.com.au as a valid email address in about a week due to excessive spam levels

Please use the enquiries [at] nistune.com email address on the main page for any direct correspondance

thanks

have to look into that one. need to check how the offset is stored/applied to the log file

It is possible for ODD/EVEN mode that it ignores the offset. I've added an investigate item on this one also

I've added an investigate item for the K value to double check against hand calc since you guys are noticing a problem with it

Any cell with 14.7 or greater cannot have the O2 sensor flag turned off on it

There is no raw value to translate it back to in the ECU.

So the next version of NIStune wont let you turn it off. Previous versions may have let you but put the cell value to an incorrect raw number

I'm having some fun (!) with the O2 sensor flag settings. I have found for the VG30 and SR20 at least that the O2 flag cannot be cleared when the AFR is between 29.4-14.82 (lean) Tried this out on the bench and monitored the injector settings in consult whilst changing the values. Confirms what I se...

no probs. someone else pointed out log files being deleted (under simpler cirsumstances) so will be investigated soon
