car hesitates..

[Vendor Defendor]

seems like a lot of the time when i take off from a stop that the car hesitates for a second.. dosent matter if i am bearly under the gas or at full throttle, seems like it thinks about going, then goes.. what could this be?

i dont know if this has anything to do with it, but i have noticed that my IAC seems to get low sometimes, it gets as low as 12... and some times it sets steady at ~40... weird

Could be the tip in stumble I've heard of with 009's you might do a search. I've never programmed 009's but I have 008's in my car and they spray a lot of fuel at tip in and I've found a TPS AE reduction in the first cell or 2 helped a lot.

so you think i should turn my TPS down a little bit? i think right now its at .44 engine off

thanks

I believe he's talking about making a change in chip programing by decreasing the accelerator enrichment in the first few block learn cells. Brian

Fuelie has the right idea. I've heard that Jim Testa has a very good handle on a 009 tip in fix in his chips, just fyi. Dropping the tps is not what you want to do. The area in the chip I'm referring to measures the rate of change of TPS and adds AE based on that. There's also a LV8 change AE addition too but niether one has a BLM reference to it.

Hey Fuelie, what turbo you running???

TE45a with a PTE .63 housing. It's just flawless on the street and killer at the track. I ran 129.59 mph on a way loose convertor 4,500 stall Artv Carr 9" non lu, and unported GN1's w/ a conservative cam. Sorry Vendor Defendor for stepping on your thread. Just got excited for a minute! Brian
