Please send me a Private Message (PM) I have a big TBI. dave w

Hey wanted to say thank you for all the help! I switched ecm to the 427 and used $OE with a bmhk bin, raised the whole ve table cuz I only have the...

I tuned for knock on the worst 90+ degree, high humidity (crap air) days that I could. Street driving because it doesn't knock at the track. Maybe...

Hahaha that killed me. Maybe I'll try bumping up timing leading up to my max. Although it doesn't feel like it needs timing there - torque feels...

with the exception of sometimes seeing lingering kr after forced downshift/throttle stab, the only knock counts I see are at startup. I am talking...

So you tune based on knock retard, not knock counts? With your current tune, around how many knock counts are you seeing in a short (say 30min)...

I baselined it with the butt dyno and then finished tuning at the dragstrip. I saw more kr on the street than at the track (varying conditions vs....

Hmm. Well, the track was only at 70' elevation, so I can't imagine that correction would have thrown stuff off too much. But good to know for the...

Most weather stations report corrected (to sea level equivalent) barometer. You need to uncorrect that reading or factor in for track elevation. I...

I pulled that number from this calculator, which appears to use an SAE standard. Corrected for what? Temperature? The linked calculator takes...

I don't think a 1700' DA equates to "100.5% of rated HP". I would expect it to calculate out at around 96%. Are you sure which barometric reading you...

Looks like the density altitude was 1,697 feet. I'm new to drag racing, but that doesn't sound too bad. According to another calculator I found, with...

do you know what the density altitude was? (it can be approximated from the time/location of your pass) could you post the timeslip info? 400 hp...

It does have the cold temp spark adder. But it didn't retard until a minute or so after start. AFAIK, the knock sensor is still the stock one to the...

Hmmm. That's something I've never heard of. What does the injector pulse width go to when it dies? Watch the log history and see if it falls off a...

I had a Vortec-headed 355 in my Camaro that trapped the same. Started at 101 and I tuned it to 106. 3300lbs race weight and I figured about 400hp on...

Ever get it running right? Edelbrock referred me to CPE too but I have not ordered any programming yet.

Sorry it took a bit to get back on here, it started raining last week and trying to finish up too many projects before winter. I increased idle in...

Please PM me so I can help.

Sweet I have em tuned out still. What I will say it was cutting out on me before the swap at random places at wot before and still was with the new...
