Is it possible to use an adruino and its shields to modernized the ecu?

is the bnr32 feature pack 2 out of beta ? Update: BNR32 Feature Pack 2 available. Same updates as I've done for R34 etc - Boost control - Boost by gear (2 x maps) - Idle fuel table (tickbox) - Latency vs voltage table (replacing latency parameter and voltage adjustment) Looking at Z32 ECU next depen...

Matt can we get a pinned thread that only you can post and edit on what changes have been done to nistune, like a Patch notes thread. It is cumbersome looking for what has changed for X board or if X feature is in beta/added/in-progress. So it would be every post is every major patch or revision.

Do feature v1 boards need another reflash or just download the new nistune software?

i have done that, i ticked the halve box and the double box, choose r35 maf 3" > commit change > OK , then i start up the vehicle. Curve is not correct in file. when doing the resize tick the 'halve' button edit: it seems i fail to read and comprehend >_< it says tick double if using the stock ...

this time around i just adjusted the TIM and left the k constant alone, but the result was the same. after i drive it and park it would loose it shit and go pig rich

clean maf, checked the wiring for connectivity issue, check for vac leak and in the log the car started driving fine then i pulled over at the house and it went rich as a pig. i would appreciate any insight to my hindsight to solve this problem. also in the change maf option it still says none detec...

Changed pipes to the greddy , changed the maf but it does not say that i am using the r35 after the changes. Am i missing something , because the car was acting up later on the day.

the afr is not really consistent, it would swing about 1.2-2.3 . I will try to do what you recommend and see about the pipes. I did not check or logged the stock setup >_< The ECU will work with an average of both sensors. Was is doing that with the factory setup? What if you swap the sensors, does ...

i am not sure if this is a problem or not, but i wired in some hitachi r35 mafs on my bnr32 with 3" x2 pipe . It seems on is reading higher than the other on the voltage and is this normal?

got it sorted out, had vacuum problems .

idk , i cannot even commad the idle above 1.2k or lower on nistune even if I change it.
i have the dwell back to stock and it still the same symptoms.

I'll check if the idle issue is related to DTC 21.

this table?

I am getting a DTC 21 and I cannot command idle , it sticks at 1.2k instead of 950. I have checked vac leaks and nothing comes up.

would something like a wrapper be possible like http://izpack.org/
