well...in my quest to build my car right, i am debating between spending the loot for a Haltech EK6 or just do it cheap with an AFC and lower fuel pressure. Right now, i still have stock internals, so boost isn't gonna go above 13 lbs. I have emailed Haltech and they said that you don't use the stock ECU at all when you put this system in... that sounds all great and dandy to me, but, doesn't our ECU control other functions in the car besides just fuel and spark? Such as gauges, A/C control, and don't even like the wires for door locks go through there? or am i just smoking crack, and the only thing i need to worry about is the A/C control, and guages?

As for the wiring issue...how hard could it honestly be? i got a damn good knowledge of how wiring works, how circuit works, where sensors go on cars, etc. so...i should be able to figure that out pretty well. It honestly looks like it would be easier to wire than how the factory harness is run.

Tuning: that is the next issue. I want to have an EGT, and a quality A/F meter. Like the modded ones wyatt has on his site. Gettin a laptop to use is not a problem either. And...there is like 2 dyno's in my area...so i should be able to get some good dyno time to get it done. But, i should be able to get it running just by tuning the closed loop mode with the A/F meter, and the WOT with the EGT and the A/F meter...then get some dyno time to really fine tune it.

Injectors: 550's would be what i would use for now...but what kind i need to use i am not sure of yet..whether it would use saturated or Peak and hold's. This i ain't sure about yet...but shouldn't really be a problem. Just need to talk to RC and Haltech on this.

Hmmmm...what else am i forgetting about guys? I know that Hahn is the only one who has done this yet...but you guys said it is a piggyback setup they use? i thought the Accel DFI was a standalone? Nowhere on accel's site do they have anything about how you can hook it up as a piggyback...if you could, this setup would be so much better. That way you could retain the stock ECU to control the little things that will cause problems.

I guess i should write to the DSM mailing list as well..i know there is some people on there that have put the EK6 on their 4g63's.

Is there any other systems that any of you have looked into? I know SDS makes some...but they look kinda cheap, and The MOTEC ones are hella expensive..but probably the nicest.

Let me know what you guys think? i would really like to get some discussion going on this topic.
