Rb25 In R32 Severe Overfuelling

[wlspn]

I have just installed an RB25 in my R32, running R33 ECU & loom modified by slo32. Starts & runs pretty good when cold but as soon as it starts to warm up, black smoke POURS from the exhaust & the idle goes all up the shit. Timing is around 20 (when cold at least), have roughly checked coolant temp sensor (resistance drops as temp increases) & O2 sensor worked fine not long ago on old engine... Any ideas would be much appreciated. Will chuck some more info up tomorrow regarding mods, etc (been breathing fuel for a few hours so need to crash) but wanted to see if anyone could help at this stage. Does anyone have resistance specs for a good temp sensor?

Cheers, Brett

Should be around 3k ohms cold and 300 ohms hot.

Check the signal voltage from the afm. It has little input while the coolant temp sensor is controlling fuel during warm up.

Oh and afm voltage should be 0.4 when engine off and ign on, around 0.6 while cranking and about 1.2-1.6v while running

plug into the consult port and watch ur vitals, has to be afm, inj or or even ignition, shouldnt take to long to see whats up, 75$ for consult software and cable at ecutalk website, or u could use someone elses, ive got one

Checked fuel pressure?

Could be a stuffed reg, mine blew black fuel clouds years ago when the reg died
