Let me know what you find out here.

3). The O2 wiring is reversed between the two

Easy switch

4). No MAF on the SRT but it does require an IAT, I'm using the iat in the maf for now but plan on changing the ground location

Can the SRT IAT sesor be installed?

5). SC clutch on Srt - I'm going to re-route to another device

A really big resistor? We will need to know the resistance of the clutch

6). No intake runner control on the SRT ecu, mine is disabled anyway

Are you running full time short or long? How did you disable it?

7). The SRT triggers a relay to switch on the IC pump - I plan on copying this configuration for my existing IC pump to make the ecu happy

I don't need a pump but do need to deal with this. I was told this can be programed out with DAS.

8). Different map sensors - already changed out - will publish the numbers later so they are readily available.

I thought they were different but have also been told they are the same. I assumed the n/a was a 1 bar sensor and the Kompressor was maybe a 3 bar.

9). I'm already running SRT injectors so no difference there!

do you see any problem running stock n/a injectors until I add the turbo?


Questions and comments above.
1). I don't have an extra block off plate as I made mine. I can make you a template easily enough. If I can free up some time, I'll see about doing another one.
2). Will Do
3). -
4). I don't have one handy but it looked like the same form factor IIRC. If I can get a better pic to confirm that it fits like the MAF, I'll order one in along with a connector and hook it up that way in my plumbing.
5). This might sound funny, but looking at the wiring, I might be able to connect the short runner solenoid to this instead and be golden. I'll let everyone know how it works out.
6). I suspected the shaft of allowing a boost leak so I disconnected the linkage and left it connected. I then locked it in the high rpm position and sealed it closed with a dab of rtv, (2) rubber coated washers, and a 10mm nut on the shaft.
7). Nice if I can disable is Das and not have to worry. I just got it tonight so I will have to play with it and see.
8). Exactomundo - Part # 68000238AA
9). I'm not sure on the size difference in the stock injectors on your motor versus the ones in your target ecu. If they are close enough you should be ok with O2 correction while in closed loop. Open loop is another story as you are dealing with pre-programmed fuel tables. The only way to know for sure is by checking it with a wideband.
