Conversion of OBD2 oxy millivolts to exh gas temp or A/F ratio
Data readily available on the OBD2 port regarding the oxy1 and oxy2 millivolt readings for the exhaust exist and can be displayed on a PDA or other small computing device in pseudo real-time. Can these millivolt readings be converted into a fairly accurate exhaust gas temp range though some formula? In the same vein, can they also be converted into an approximate air-fuel ratio through some other formula? I mount a PDA just above the turn signal stalk that displays nice graphs and values from OBD2 (calc. load, air intake temp, oxy1, oxy2, short term fuel trim, etc) from some freeware at http://www.qcontinuum.org/obdgauge/index.htm. It seems to work well, but the oxy sensor readings don't mean much to me in "millivolt form". Wondering if there is a way to do a quick convert while viewing the millivolt and/graph readings to come up with EGT and A/F if possible. Thanks a bunch in advance.
Are These questions just for SRT4 owners or all SRT owners?
If it's for all SRT owners I have one big question.
Why is it like pulling teeth to get a number to the SRT division?
You say it's not!
Then go try and get it!! I challenge anyone!
Chrysler is so hush hush about everything it boils my blood!
I wish I didn't like their vehicles.
I have a question about a car I paid 40,000 for and I can't get a phone number!
Please don't tell me to call so called Chrysler Assistance. Please!
The dealer! C'mon!

Can anoyone post 3 questions for me reguarding the SRT6?
I would really appreciate it.
1. Why is the SRT6 only produced in a slushbox? The regular crossfire is available in manual and it seems such a shame for a car that is otherwise perfect to be so marred.
2. Why does the crossfire SRT6 have 20ish less horses then the SLK32 AMG that donated the engine? Could it have been/can it be tweaked to produce the same power? I thought you guys were the power gods, only to find out the germans got you! Tell me it isn't so!
3. Stage packages/ Aftermarket. Are you going to offer anything at all for the car? There is not currently a single aftermarket (performance) part availabe for this car - which seems to be you'ze guys department. Please at least a pully and a tune! Pretty please!

#2 Every car in U.S. spec has at least 20 less hp than it's original german counterpart. The U.S. has the strictest emissions laws, hello.
#3 Not a single performance part? Did you look for compatible slk32 or kompressor performance parts on the german market? I think I've seen a couple modded kompressors around here.

Yes. . .but they SELL the SLK32 AMG HERE, and the US version has 20 less horsepower. So what I'm really asking is if the differance is packaging problames or brand seperation.

Thats right. not a SIGNLE SRT6 performance part. I didn't want to buy (ultra expensive) merc parts that may or may NOT work if the SRT engineers are capable of making a Mopar part.
Along those lines, WOULD Merc aftermarket parts work with the SRT6? That would be helpful to know right from the engineers.
Is there a contact number for the rebuilding the S2 PCM?
**EDIT**
Due to an issue with the maps in the S2 PCM, the dealership believes that the S2 has an issue that requires replacing the S@ PCM. Currently, the only way to replace it is to buy a totally new kit. Is there a contact # for the manufacturer of the S2 PCM or at least someone who could help with fixing/rebuilding the S2?
This may have already been asked, I have a stage 2 upgrade. Will it hurt my car if I leave it in dial 2 or 3 all the time. And dose it hurt my gas mileage? Thank's for the time.

are any drivetrain upgrades by mopar going to be availible? i'm looking specifically for a 3.18:1 final drive ratio, for a bit better mileage on the highway, as well as improved 1st and 2nd gear traction. any plans for such a part?
