Re: ultimate chip ?

i think that the security one is a must as i have youwt drivers in house that might take truck for a joyride with their friends!
and then maybe 2 or 3 street modes with varying higher degrees of boost levels if that is how it works, i really dont plan on taking it to the track but maybe once just to get a real time slip for what it runs .92 octane only, i wanna go street race some this summer and it is in no running condition for that till this is done.

dig can you pm me with a ballpark of what you will charge me to do this and when you might want to tackle it?

thanks tim

Re: ultimate chip ?

OK feeling a little retarded , I got truck out of storage and was irritated about my UC situation so i REREAD the installation sheet and completely overlooked the put stock chip ON the ultimate and then install it in the ECM !
well now it works like it is supposed to. It has a slight knock registering on the chip light.
so for shits n giggles i filled wit 92 and dumped a half gallon of xylene in to see if it would go away, but i think the cleaning agent plugged my filter . it starts , but dies as soon as i go into gear.
something else i noticed is, i read that the stock injectors had red tops and mine are gray so i looked them up and they are 40s , so is that going to be a issue with how it runs too?

changing fuel filter and installing 02 gauge tomorrow

can a new chip be burnt for 60# injectors for the ultimate ?

Re: ultimate chip ?

so i installed a o2 gauge in truck and a wot it was pegging the gauge rich so i checked fuel pressure and adjusted to 41-2 #s now it is better at 10.8-11.2 @WOT . truck pulls pretty hard just a slight lag at the bottom probably from the injectors being 40s instead of stock.
should i put smaller injectors back in it ?
only other issue is after the truck has been running and then shut off and allowed to heat soak a little bit when the truck is restarted it doesnt want to idle over 550-600 rpm and dies when pulled into gear ,any ideas?
thanks tim

As far as WOT looks ok.. Keep it around 11.2 if possible.Check the BLM numbers at Idle as well as the IAC counts.Look for 128 BLM the higher the number the more the ECM is adding fuel the lower the number its taking it away,to roughly get a 14.7 air fuel mixture.You can manipulate the fuel pressure as a poor mans way of fixing it but wont be perfect either way.WOT is more detrimental.
