t link numbers crazy

[crazygn]

I ran the car last night to tune it in at 15psi. I ran it at 39psi with the vac lin off , [fp] . The o2's where in the 780's in 3rd then they die to 100-200's but the fp is good by the gauge under boost. My beems are at 105 all the time, so i tryed to drop the fp to see if it ran any better, i got it down to 32psi with vac off and it ran the best, but the o2's still read 780's and the beems are still 105. no knock at any fp, something cant be right here. Maybe my t link is reading wrong and ive been pig rich.

why would the t link read crazy numbers and give false info on and off , it even said i was doing 151mph in about a 1/4 mile run.thats crazy.

I seen this on my buddies stock 84 ecm,it turned out to be fried,it was also saying the was 20 something degrees of knock at all times while running.

It does that to , says iam getting bad knock sometimes like 30-50* of knock retard.

Iam hoping for a bad ground or something , i do think my o2' sensor is bad and i have a bad header leak.

On my buddies car we swapped in a known good ecm and it was back to normal.I should also say that this ecm that quit was a new unit from GM with a stock chip.It quit for no reason whatsoever.Strangely the car ran pretty good for normal driving but it would all of a sudden go into this spitting,backfiring and jerking under full throttle from a stop.

Let me know what you find out. My turbo-link numbers are all over the place. Once in a quarter mile, I only had about 2 frames of info. Other times it reads open loop and the miles per hour and retard are all over. It seems to run fairly well, though.
