My 6g74 tt build

i am currently running 2 piggybacks... so my response would be, people dont. i think the flashable ecu is a better setup because you have direct control rather than tricking the ecu to do what you want it to do. i have a flashable setup on the shelf at home, but i have other priorities currently

ray was the one who convinced me to go with MAF-T & SAFC...and that's what i'm planning on using.

If you like things simple there is nothing wrong with that.

thats what im using as well. however when i plan on stepping up to 1000cc injectors, i will need a different method of tuning. i would also like to get into the realm of playing with my timing a bit

AEM is for you. Complete control.

no thank you. i know the direction i want to go

Any experts on wire harnesses here? I'm debating which route to go with the harness/ecu.

I want to go with one of the chromed flashable ecu's. These have ecu harness adapters available, but they were designed for tt cars. I asked Brett about it and he said he could make some custom harness adapters for my situation. I'm wondering if it would be easier to just buy a 98 or 99 vr4 harness and then I shouldn't need any adapters, right? I also hear that 98,99 sl harnesses are very similar. Could I use one of those? It's probably going to be hard to find any 98/99 harness, so I was also thinking, would it be so bad if I just bought a 94 or 95 vr4 or rt/tt harness and ecu? This would probably also save me a good bit of $. Is there anything else I should be taking into consideration? Will my dash and body harness be ok? I'm not worried about ABS or ECS, so that's not an issue. At this point I don't really care if I have the boost gauge in the dash. I already have an A-pillar pod and boost gauge I could use. Also another question about the dash harness, this is where the obd2 port sits. I know it's a hybrid setup (on 93-95's i think) but will there be any wiring issues with this? The wiring was all good for obd2, just the ecu wasn't right?

Sometime in the next few days I'm supposed to go pick up almost everything I'm going to need for this conversion
The harness issue is my biggest dilemma at the moment.

Also to add to the chaos, either before or in the middle of this project I'll be installing the keyless/proximity entry and push-button start setup.
I believe this will primarily tap into the dash harness, which is another reason I want to figure out my wiring questions soon. I don't want to have to install this kit twice.

Well, right now dude I'll be transplanting in a 1991 DOHC harness, then using the converter to go 91 > 99. Means so stuffing around for me at all. plug it in, and (hopefully) off I go!
On this topic, the tactrix 1.3 cable is good for datalogging only ya?

[n2nsanity]

As far as I know only for logging. Can get a 1.3 or equivalent for $20 or $30. If you want reflashing capability, you need the 2.0 which is $170 now I think.
Or am I backwards on this?

I want to do all these things but I wonder if there's even a need on mostly stock tt stuff (minus the 10:1 compression and the GM MAF)
I'm not sure what to do now. At least not until some of my harness questions are answered.

[n2nsanity]

Updated my parts list. Have almost everything I need now

These will definitely get some TLC before installing
