So, where do I start?
« on: October 14 2012, 10:28:59 AM »
Starting a new thread because I dont want to stuff too much info in one.  This thread is going to be about my attempt at WOT. Anywho, the TPS voltage at WOT checks out at 4.3 after adjusting the TV cable. I attempted WOT last night on the way home from the bowling alley. I noticed that the max boost my car is running right now about 11-12 lbs.  I looked at the gauge like WTF?? When i first installed this chip I know for sure that my car was making 17 lbs because I vividly remember looking at my boost gauge fly to 17 lbs instantly and it scared me.  Lol.  Sooo, Im assuming I unplugged something when installing the T-Stat. Going out now to find what could possibly be the problem. Keep you posted.

The wastegate Solenoid had gotten unpluggeed. :hmm   Thats what I get for working in the dark.  I have question though. Because I went WOT with that being unplugged, wouldn't my car have run a bit richer? I mean, the chip was designed for 17 lbs of boost, and with that being unplugged, it was only making 11-12 lbs. My 3rd gear WOT 02's were really low(730) but i let out of it.  I had no knock during the pull though. Well, the knock showed .2 but quickly subsided. Any thoughts?

I would have thought that it would have been rich...

Is the boost coming up now?  Re check it and be prepared to let off if the o2s are still low...fuel pressure should be 43 with the hose off...that where you have it after all the playing?

If it is, then you might reprogram the wide open throttle and change the setting from 128 to 134 before you go wot again

A lot of broken parts does not make you a racer; it makes you a slow learner.

Phil, have you replaced the 3 rubber hoses wastegate solenoid circuit yet?


If not, you REALLY need to before doing anymore WOT tuning.

43 psi line off.  And yes, the boost is coming up like it's suppose to. 1st gear reading after a little run just now was 824 for the O2's and zero knock.  I know 1st gear isn't as critical, but its all I have for now because Im not in a good area to test 3rd WOT runs.

Those hoses are in good condition. I checked those when I was redoing the vacuum lines.  They still look good.

The instructions say to set the FP +- 5 from 43 psi line off. I was thinking of increasing the FP for WOT through the Translator.

134 would be a +4.7% increase in WOT fuel?

Yes, looks like you are reading the instructions!  If it was 824 in first, leave it alone and try it in third!  824 is on the rich side.

Leave the translator alone...that is why you have a programmable chip.  Normally, it should be set on the default positions if the car is in good condition

Phil...remembe r that when you were messing the fuel and the translator before, the engine was not right due to the timing gear so set the translator to the defaults and try not to change it unless you are unable to get it right with the chip
