Shiv,

My prototype exhaust should be done by weeks end.
I plan on then installing the PROcede.
I have a few questions, maybe some forum members can share thier thoughts as well, which is why I'm posting and not PMing.

It will eventually be a full TBE, but at the moment the exhaust will be from the DPs back.
Center cat deletes with 12" perforated resonators.
It will probably have some type of cross over added in, as we have a slight drone from 1,700 to 2,400 rpms.

1: Is your performance file different for people that have a more breathing exhaust ? or does the PROcede just adapt to it ?

2: The car runs very rich, stock. Does the file lean it out a bit ?
I have not seen any AF charts with any of the dynos from the local Tune days.

3: What does the file do to the stock 8psi boost levels ?
Is it just a pre set boost level ? or does the boost vary depending on RPM ?

I think that's it.

Looking forward to getting the car, even more fun to drive.

Thanks,

kj

GOOD QUESTIONS.... if im not wrong i think the boost goes up by 4... but i could be talking Gibberish

2. The car actually runs very lean compared to other turbo car. The A/F ratio stays around 15:1 all the way until 5K under WOT, and then it moves to 12:1. This is why direct injection is so nice, by spraying fuel directly onto the top of the pistons right before ignition and getting better fuel atomization, N54 is able to run so lean without detonation. My rx7 and subaru's turbo cars had to run 11:1 under full boost pretty much though out the entire rpm range.

3. Yes, the boost vary depending on RPM. You'll have to get the boost curve from Shiv.

Thanks for the info thus far.

the procede runs much richer than stock its almost 14:1 by the time it hits 3k and < 13:1 after that

Hey man, I noticed you were from California. Be careful with removing cats. My friend got busted with deleted cats and California whacks you some ridiculous fine for messing with cats. Literally he had to give up his vehicle to pay the fine.

But otherwise, sounds sweet!

^^ WTF ive lived in cali my whole damb life and have never had a problem with it!!! the only time its a problem is SMOG time!! which in that case YES u have to put it back to stock or it wont pass! I dont what the hell your talking about them taking his car that sounds to me like it was a POS!! maybe it needed to be taken off the road

I think everyone pretty much answered your questions but here goes anyway...

1) The PROcede map for a car with an exhaust is different than the map for a totally stock car. So you will want to run that. We'll have both on our website available for download along with the software shortly.

2) The stock car runs anything but rich. Even at high rpm, the richest it goes is 12-12.5:1. In the low-end and midrange is stays right around 15:1. The PROcede makes it run considerably richer, often as rich at 11:1 up top. This is good.

3) The PROcede bumps low end boost to roughly 12psi. It stays between 11 to 12psi until 5500rpm and then tapers down to 9-10psi by 7000rpm.

Lemme know if you have anymore questions...

cheers,
shiv

Thanks everyone.
Thanks Shiv.

I sent an email to your website, with questions regaring availability and possibly installing at Harmann Motive.

Feel free to answer that emil anytime and looking forward to my exhasut being done, to PROcede the car.

Thanks,
kj

My man, you need to cut down your caffeine intake. Now I don't know the whole history of what happened to his Z06, but I know he wrote a very large check.

Read up on the Health and Safety Code as it relates to C.A.R.B. The fine can be up to $2,500 per day that you violated CARB rules.

Do the math. It adds up fast.

That's why when you decide to remove your CATs, replace them with a through hole CAT design (fake CATs) so when the cop shines his flashlight under your car, it will appear your CATs are there.

One more question.......

What is the maximum boost the stock turbo's can handle ?

Shiv,
I'm installing a catback this weekend. Do you happen to have a 93oct map for a car with a catback that is ready?
Thanks

good question, as I'll have a full DP back, cat delete system on my car with hi flow DPs to follow.

I'd love to have a file that takes that into consideration, but I'd still love leave the boost a few psi under max, for longevity and to make sure there are no problems that BMW will then have to look into..

I'd assume with a full back TBE, the boost could stay up at 11-12 throughout the range , no ?
