Rb20 Nistune Computer And Z32 Afm Issues

[GH05T]

Do what they say!!!

[Luke HCR32]

Did manage to granny it there with the injectors, ran rich as and was fouled to shit by the time I arrived, old spark plugs were stuffed anyway.

Just a warning on the ceffy computers, the tuner actually had to get the developer of the Nistune in to try and sort it out, apparently the ceffy/laurel computer has a slower processor than the 32 and also for some reason will not hold AFRs as consistently, I traded mine in for a manual 32 gtst computer.

Also if anyone has a 32 computer with a black (instead of blue) sticker these have a faster processor again (usually only found in the 1993s).

Currently making 197 rwkw @ ~17 psi but injectors are playing up a bit.

Is there anything wrong with running a Laurel computer?

yes the are crap, we wont nistune the A31 and C33 ecu's... we replace them with r32 ecus (plug str8 in)

All the c33 and a31 ecu require a type 1 board not the type 2 nistune board that the r32 ecus take. The r32 ecu are farmore modern and take to tuning fa better.

i have a C33 myself.

Actually these computers are virtually identical to the HCR32 ECU. Problem is that the A31/C33 ECUs dont have consult capabilitiy which was the main difference (so the normal lines for consult RX/TX/CLK dont exist on these)

Type 1 board 'USB consult' was adapted these ECUs but tuners reported AFR inconsistencies with A31s so we have dropped using the board with those ECUs in the meantime until I investigate further. I suspect some of the extra code added is clobbering the ECUs internal variables so I need to go through that ECU patch firmware again and try and workout whats going on. Would be good to get those going since I have a stack of A31 ecus here and they potentially could support RB25
