Im running an alky chip but for the race gas runs i turned the alky off to try to figure things out and narrow that out. the Race4 log was from a dead stop buiding boost then launching it. i know i need to pull fuel but thats the least of my problem right now. as far as the TPS on the pump gas i didnt want to get into it fully. still trying to figure out why it knock only on the 3rd to second down shift. the MAF looks kinda fishy. it throws some weird readings.it reads low and never goes to 255 and it seems slow to respond. with my motor that thing should peg 255 no problem.
Still got knock please help

Agreed on the MAF looking odd... Got a spare or one you can borrow to try it out ?? I'm also pretty sure that with an alky chip you dont want to shut the alky off!.. Fuel and timing curves are different then a straight pump gas or race gas chip
yes fuel and timing curves are different but Eric didnt seem worried about it being off. the a/f looks good under WOT its alittle rich and timing is low so that race gas will be fine. as far as a spare MAF i got one i can stick on there for a few runs.

Chuck,
What do you look for when reading the plugs?

plugs look good from what i can tell. torque on the knock sensor is 14ftlbs also tryed changing it out. i bumped the TPS up some since i didnt like how low the WOT value was. im going to put a different MAF on it and see what happens.

Here's some good..
places to start: Great pics, and good description as to what's doing what!! :O)
Here's 1...Spark Plug Reading 101 by Mike Canter
#2.. Spark plug reading
#3. This is the one I like...Spark plug reading
I use an otoscope to read plugs.. $25.00 on e-bag. It's actually a medical tool that dr's use to look in your ears:O)
Have a great T-day!

ok i got 2 more logs. the knock has to be false i dont hear it and im runing C16 anyways no more 2nd to 3rd down shifts till i get another chip. also it runs damn good. these logs are on C16 no alky. i think i need to turn the timing up but i will do that at the track. right now alittle more boost and some timing and this think is going to move. anyways here are the two logs
