SQ maf gonzo

[|Maku|]

Hey guys!

We are having a problem here with a car that uses SQ maf. Car has SQ maf with resistors, changed cooler, manifolds, turbo, 444cc injectors etc. The problem is that when I release the throttle, motor stops working. It doesn't happen every time this way, but it happens quite often. The thing is that we took for on approval Hamon-Motors software that supports orange injectors, SQ maf, 300kpa MAP, it looks like something is wrong. One fellow who owns a car with MTM 420ps setup, told us that when he disconnects ECU, car doesn't work properly for a long time and then in some point it starts working again. What I want to know is that does SQ maf has some kind of gonzos (individualized qualities) so that ECU needs to learn setup a bit longer? I know that with usual maf motronic learns setup for about 100km or so.. But is there anything different with SQ maf?

Thanks,

Marko

Anybody?

I have heard, that there might be problems with SQ MAF installed, that software is not tuned property having this kind of hardware.

I’ll have soon SQ MAF as well, but together with DBR sport software, which is checked out in reality and fully recognizes SQ MAF and works without any problems.

I cannot suggest to you anything special, just my opinion is: there has to be total accordance between ECU and “hardware”: injectors, turbocharger, MAF, MAP, fuel pressure etc.

if you are going with the SQ maf you will need for sure the required ECU setup for it may you problem is it ,try with the RS2/aby MAF THAT BOTH ARE THE SAME, or with the 3b/aan that both are different

I'm not quite sure adu/aby MAF’s are the same
adu - 034133471N
aby - 034133471K

Electronically they are the same, the difference in part numbers is because the RS2 MAF has different screens.

SQ MAF has different characteristic (volts output for mass air input) versus S2/RS2 MAF - the ECU needs to be remapped for the different profile. This is a very specialised task - I have not unlocked how to do this yet, but I'm getting closer.
