Hey b

With the Stage 2 reflash...


550 CEL free miles w/ the PDE down-pipe

20 miles with the Cobb down-pipe and I got the P0240

Car starts just fine and I cleared it....but it's the fact that it threw it in the 1st place.

 

holy crap. that is f'd. how would the 2 dp designs change what the cat o2 sees? damn. my txs dp is the same design as the cobb w/ the big opening.

the question is, did your car have a hard start like mine does after the code clearing? b

 

1) No, my car is still smooth.

2) The PDE had a cheat pipe that the Cat O2 goes in..... the Cobb doesn't.

 

damn, it has a place to shield the o2 sensor? makes sense now. but i guess our ecus are still different. i still gotta take a look at my ecu #.

so cel is due to dp design, but hard start is ecu prob.

Revised STi Maps. v1.02 are out.

 

hey dan. do you know what fixes are in the 1.02? thanks b

 

2 days so far on the 1.02 and no cels yet!!!!

yay. b

 

Really.........did it fit that hard starting?

 

nope, still had a hard start(exact same), but hopefully if the cels don't come on, then i won't have to experience the hard start issues as much.

still gotta see if the hard start occurs when switching realtime maps. so far i just have the basemap on and haven't messed around with the real maps yet. so i am not sure if switching inbetween real maps i'll have the hard starts.

b

 

That sucks....I'm getting the CEL but no hard start............I'm off to switch to the new map!

 

you still on the old map? if this doesn't work, i am gonna get a pde DP or that housing extension for the sensor.

oh well, my "new" rims are keeping me happy. i might actually have to wash my car for a couple weeks now. b

 

Just loaded up the 91oct LWG stage 2 BASE map........went in fine and started with no hesitation.

Hopefully no more cat CEL.

 

yeah, but yours never had the hard start problem.
still no cel yet for me.

I know, that's what's so strange. I'd like to know why you do.

When Pat gets back, if we can swing it, I'd like to run delta dash logs of both our cars to see what's different.
