Got a text from Chris Smith Racing a couple days ago, asked if i could lend a hand with a BMW E90 Continental Challenge ST car. Sure, why not!

a good friend and local Nasa racer Jason came and helped out on Saturday, put the heat shield in

Just needs a couple more bits installed/fab'ed up, then entering a 3 hour Enduro on Friday...

two questions...

1) is this the first race for it? Looks like it's just getting finished.

and 2) is this the car that had it's own thread some time back? Where a group of people got together an decided on making one. Or was that a silver car- I can't seem to remember.

Good luck with it, I'm sure we'll see it in a few weeks on TV. hopefully, not as the cause of a yellow....

Answer both questions: YES

First race is gonna be a shake down for it.

This started life as a silver E90, two Spec E30 dudes bought it with intentions of building a ST car out of it. Got it shipped to CSR for Chris to finish.

Cool- I'll root for it, even though it's a BMW.

Although, by the time I see it, the race will be long over.

So, what ended up being the ECU plan?

(BTW, reading through the old posts, pigeon thought the tuning software was INPA or something close to that- it's actually INCA- which is Bosch tuning software- they let all of their customers use it. I never used it, but know people who have, soo... a very minor correction)

they ended up going with the bosch motorsports box - $7,500...

That looks nice. My BMW in my garage is:

a. Older. b. Rustier. c. Slower. d. Has the to-do list taped to the right rear window instead of the left rear window.

UPDATE

Well, after being at the shop until 1:30am doing corner weights and stringing up the car, i get back to the shop at 5am to load up the rig and get to the track. Found out last night that the crank position sensor and cam position sensor, which look the same, are two completely different sensors and was making it go into limp mode. Corrected it, fired up.

First session of the day: Completely chews the serpentine belt and destroys the tensioner. I ran to Advance at least 5 times to and from the track to get the correct tensioner (incorrectly packaged by the vendor) and right belt (half an inch off makes a world of difference). So, after 2 hours of tracking down the correct parts, go out for the 3rd session. 2 laps in, pop the hood, oil is EVERYWHERE... At first, we thought the shredded belt got wrapped around the harmonic balancer and wedged itself into the crank seal, but found out it was the crankcase ventilation pipe had come loose and was dripping oil onto the belly pan, which when Jim got on the brakes, would shlosh forward on the pan under the crank. Easy fix.

Now, to iron out all the Motec stuff and a couple more sessions, should be an awesome car!

On the Motec side- do you have someone dedicated to do that work? Not that I know anything about Motec, specifcially, but if the specialist is up to their eyeballs fixing other issues, I can take a look at the engine running data to provide some suggestions.

Assuming you are taking reams of data to be looked at.

Good luck with it!

Yeup, we have a dedicated Motec guy. We spent 2 hours on the dyno two days go, fine tuning everything. It is definitely something i would like to learn. Currently learning the AIM systems.

Cool, and I hope you all continue to take data while the car is on the track. 2 hours isn't all that long to tune. Should get close enough for most situations, but there may be some where the dyno isn't quite right- say part throttle situations, and transients.

So as long as you can continue to take data to fine tune, you can make that thing sing.
