Thread: DET Flooding out?

New ECU and tune, same issue. Tried a different MAF aswell, I have a good ground and good 12v across the MAF wiring. I dont think there can be anything else... runs awesome after you pull the fuel pump fuse...

Did you wire the injectors up correctly?

i had a problem with my z32 maf as well, never did understand it...hence the swap to standalone and map. If it runs on one computer and not the other you need to find out what the differences are in the tunes. Set up compare in tunerpro and go through everything, might be something as simple as your warm up enrichment settings.

Wired in a new Z32 MAF plug tail and now it stays running, misses but it will stay running. Still running really rich and when I turn off the engine and take out the spark plugs I have a small amount of standing fuel on top of each cylinder. Here is a little bit from ECUtalk log:

My timing is really high and needs to be adjusted but should by MAF voltage really be that high?

New MAF, still seeing WAY too much voltage going to my ECU from the MAF, anyone have any ideas?

Double check the wiring and check the voltages as per Z32 fsm spec. Going OBD1 on P11 I had some voltage issues myself, some of the lines where shared and not sending enough power to the TPS sensor, etc. Could have a similar issue where you are sending too much to the MAF.
