Sorry to not update. It was just too costly to get the plugs made that I would need to do it, and it wasn't worth going to every junkyard in the area to get every ECU and plug to do this. Considering I (ASP) have only been able to sell 1 SOHC turbo kit even at a lower price point than Hahn but with more features and power, I'm very reluctant to dump a couple grand into this project to see $400 come back.
Hey here my almost ready to go plug n' play harness for srt! Will run very soon!
Looks just like the one i'm working on. Looks good man! I had the hardest time finding the stupid pins...Oh and getting the PCM side connector is a pain in the ass....
Read the coolant and IAT and still get the dash working
Read stock NGC
Fan driver
Boost control output for AEM solenoid
Fuel - spark : 1 table of each for begin
Already have the Cold start run great on a 2.4 T so i wil be ok
577cc tune & 682cc tune
Stage 1 or 3 spark table.
Lauch control & flat shift control
Adjustable REV limiter.
Antilag is now present un Hr11C1
New update on temp reading whitout bias resistor. I have do some test and i think i found the internal bias resistor value of the Dodge PCM
Test was so with a 10k Resistor on the coolant plug.
Here result :
Open circuit= 5V so the PCM use 5V for temp divider.
10k resistor in = Voltage on the resistor = 3.565 and the real value is 9.87K
I draw across the circuit is 355 uA.
So: 5V - 3.565V = 1.435v / 355uA = 4042 Ohms!
If i use only resistor value:
3.656V / 9.87K = 361uA
1.435v / 361 uA = 3975 Ohms!
The internal resistor for bias is 4K.
It's time for Easytherm now and check if the value is like the pcm reading!

Awesome news! Now the flat shifting is that for Wide open throttle shifting where it cuts fuel and spark for the time you shift?
Seriously, if you don't have electronics skill....go with Diablo!
MS is a lot of time..but i love it
Very flexible and cutomisable.
i haz ultimate skillz with a soldering iron.
i put a jaw unit together(easy)
the only problem is a ms kit with all the stuff for a clean install will be about 300$
and the diablo can be had for 320 at certain renegade dealerships
NOT trying to thread crap really just trying to discuss the pro's and cons
If you have a race or radical street car and aren't real concerned with passing emissions a MS (or any other stand alone) will give you a lot more control. You'll get things like 2-step rev limiter, programmable input/outputs for things like nitrous/water injection control, etc.
However, for a mainly street driven car that needs to pass emissions a diablo or SCT setup would be better.

Sc-6152SP and MS run very strong.
