The reason you're pulling so much fuel is that you're spraying too much alky.  You need to find the instructions for adjusting the turn on point of the alky and make the alky come on sooner rather than later and go back to the original setting of 6 for the amount of alky that is spraying.  Looking at the logs now

The chip...and injectors...al l came from Eric. There should be a number on the chip...which should give Eric the date he burned it...and that should tell him the brand of injectors he was selling at that time.

Thanks guys!!! Ill try the turn on point adjustment !

Looking at Erics site he sells Siemens/Mototrons...so he's likely sold them from day 1. Not sure if I sprung for the flow matched set...but I likely did.

Thanks again!!!

Some more files from testing....... frustrated. Have FP set to 43 on these, added 10% fuel to first, have almost all removed from overall, set at 106. Alky dial set to 8. Cant launch this thing without screaming alarm. Cant race it like this. Might just give up until I can get a chip for my combo

So no knock on the roll in at 8
big time knock on the 1-2 shift and tires broke free on the launch at 8
knock on the 2-3 shift on the high gear 8

Makes me think knock sensor is hearing something in the tranny, especially on the 1-2 shift.  Maybe your down pipe is hitting the pinch weld seam of the fire wall and the floor pan.  After resetting the ECM, how long are you driving the car to let the chip learn? The reason I ask is that your BLM started at 131 and went to 140 on the drive stopped file.

Jason, looks like you think its false knock. Eric Marshall agrees and so does Julio. Probably have 30 minuets of driving since ECM was reset on that log. Raining again today, never stops, so no testing. My heart really wants to race this weekend but my head it telling me to wait for a chip for my combo and start fresh. Hope to get it ordered today.

Wait and go in without any doubt.  I can tell you I ignore a lot of KR in my TBSS - damn solid mounts and race built trans.  Heck, on my last pass right as the TCC locked up - tickle of KR.  Why was I confident to ignore it?

1. Fast decay rate (ie. timing pulled was not sustained throughout the run);
2. It was in the same spot/time and roughly the same amount (ie. at launch, on a shift, some other silliness) not influenced by changes to the timing table; and
3. Fuel quality (94 octane base + a can of liquid Schwartz octane booster, 35% ethanol, and propane injection).

Looked at the file late last nite. It's hearing something 4 frames after the shift point. There's some slight KR after...almost like something's loose.

[Shimy87]

Just got out from under it again. The down pipe had about 1/4 space between it and frame, 2 inches between it and seam of firewall and floorpan. did some adjusting of exhaust and now created about 1/2 inch between frame and pipe. Also found a spot on pass side section where pipe goes over axle that may have been contacting rear coil spring?? adjusted it over as much as I could.  Have a chip ordered from Eric.

Was looking at the file, launch at 8, what I'm hoping is that the first big spike is at the 1-2 shift, maybe the DP hits hard there, and then the 2 small spikes at 82 mph and 90 mph, maybe the rear spring was hitting as I hit bumps in road.

Really appreciate all the help guys!!!

Were there any witness marks on the pipe or fame showing a hit?

[motorhead]

I was dealing with false KR when my TBSS's exhaust was smashing into the tranny x-member; made a little stand/rubber isolator to pick up the slack.

[Shimy87]

It looked like it might have made a mark on the coil spring, at this point anything that even looks suspicious is getting tweaked. With a poly drivers side mount and a good pass side one I cant see the DP moving 1/2 inch and hitting, but something is!! I'm contemplating attaching some rubber on the frame where it would line up to prevent metal to metal contact if it does swing over that much. Checked the belt tensioner and no marks on anything, took belt off and bearing is a little loose but good. On my car the tensioner pulley misses that ac bolt by 1/32 with belt off, so even if it did swing over that far it misses.

Converter clutch rattle?

How could I determine that
