teardown has begun!
The hard start, im not sure, could be a result of just more tuning being required for the cam, I did find something interesting in HPT which I dont know if this is a read error or not, the cranking ignition timing seemed to have some sort of hole smack in the middle of it of -10 degrees, smooth this table out helped alot.
I asked about tapshift to find out what rpm the cam falls off at, I know it will keep going till you shift lol. I'm tuning illiterate, I cant tell what that chart means at all. Sounds like some trial and error coming up. you will get it I'm sure. Gonna make a trip to Englishtown soon?

spawne32@comcast.net im open to comparing files, I can't VE tune the E67 ECU easily so im MAF only right now, not until HPT 2.25 comes out will they have simulated VE tables that you can actually use without using an algorithm to come up with the new numbers across 50 different tables. lol
Oh I have no idea where it dies off yet, I'll make that determination of where I want the rev limit to be based on the dyno charts at the end of the summer. 6200rpm though seems like a decent place to start, if i want to take it any farther above 6400 Im gonna want BTR pushrods and the trunion bearing upgrade on the stock rockers. Ill be heading to atco hopefully this week to face off against my buddies GTO.

Verdad Gallardo FYI all you have to do is email support for 2.25 but wait a while though cause the 2.25 scanner still isn't functional. So you have to pull your 2.24 scanner results into excel and fill the blanks with zeros then copy paste multiply percent half into your table.
Did you teach yourself how to do all this thru trial and error? I have no knowledge of this type of vehicle programming at all. Seems very confusing. I know the software is about 500 for the package maybe more, down the road this could be something I would think about doing. What is the difficulty level of learning this type of programming?
Not sure really, I kinda expected it to be faster then what I'm feeling, but given what I know about these thing's stock, I can understand why they were so slow right out of the box. The 2.93 gears must have been awful on this car, because the 3.29's are almost just as annoying. Without a power number from a dyno run yet its hard to say but id predict high to mid 13's so far with the power im feeling, it still has alot of potential to pick up with tuning though, was running considerably low ignition timing (in the teens) on the low octane tune and still was getting KR. Once the KR is cleared up, 93 is in the tank, and im hitting that 28-30* of advance at WOT, then I think the top end is going to be nasty, just then I might have the potential to pull a low 13 number, with the LS6 intake manifold down the road, and a little luck, might even get into the 12's.
That's good. I have seen some times of stock cars dipping into the thirteens. Never ran mine, not sure I ever will really. Mine feels like low fourteens. I think your goals are attainable for sure with traction. Good luck.
another vid for you guys
also figured out my open loop fault error i posted about in the PCM tuning section, apparently disabling P0300 random misfire code does not prevent the pcm from setting a fault for it, so at idle it kept going into OPEN LOOP - FAULT because it kept detecting misfires from the cams overlap. Raised the threshold on misfire detection by 50% and went right into closed loop normal.

No exhaust and no cutout, i like stealthy and this is about as loud as I want it. Can't really hear a thing inside the car other then the motor shaking or when you really get on it, its perfect. Tires I havent swapped on yet, I have to get a new TPMS sensor for the drivers side front, gonna be doing that this week. I'm loving the silent but deadly nature of the car, had a F150 try to pass me today because he didnt like me doing 10mph over the limit, wasnt fast enough for him, and when he got next to me i put it down to about 50% throttle and it broke the tires loose fighting the traction control and lept forward about a bus length. lol The 93 octane and high octane table for spark advance brought the car alive, and the top end is really starting to shine now.
Well that cam is noticeable, it doesn't really scream stealth lol. I think you will be really hurting times thru the stock exhaust if that's your goal for the car, but I totally get not wanting loud or droning. Those tires look nice, well priced as well so keep me posted on traction and wear as they could be my next set.

So you replaced the cat? If so you are probably good. The mufflers are restrictive as well as GM has to please all with their choice. I think 300 may be possible with the addition of the intake and throttle body. Your knowledge of tuning will go along way as well. Numbers are just numbers anyway(unless your running hot lol), if it runs well and you enjoy it that's what counts. This car is coming out great.
