ecu modding

[IPD]

hyper, my advice is to just do a lot of thread reading. there is a lot of info on tt-conversions, and you should familiarize yourself with all of it. know the differences between a tt-conversion and a tt-swap--and how they may be modded differently. read up on how to wire a TT-ecu to the TCU (lots of wires, but only a few connections). determine what kind of power you want to be making, and plan accordingly; sometimes this means selling your car and buying something else. educate yourself on the cost of owning and maintaining a car with the power you wish it to make....because it's not a liner correlation. understand the advantages and disadvantages of n/a vs. tt and fwd vs. awd.

most of all, calculate how much it will cost to keep the car in good working condition at all times (60k service, weatherstripping, fluid-changes, etc). that cost should be subtracted from whatever money you feel you can spend on the car. if after subtracting those costs, you do not have enough left to do a tt-conversion---then don't do it. nothing is more of a dream killer than a half-fixed, half-broken car because you over-extended yourself.

it's better to be slow, pretty and reliable....than fast, broken and expensive.

And, if you currently have a 10:1 CR N/A motor with low compression but are considering a TT conversion, you might want to consider getting a good used TT engine. At least it will have the lower compression ratio you need to run more than about 8 psi of boost. The bigger turbos (of whatever size) aren't going to give you the full benefit of their flow capacity because a 10:1 CR N/A engine can't take boost greater than 8-10 psi no matter what you do for tuning. So, rather than putting money into fixing your N/A engine, just buy a TT engine. Just my 1.5 cents worth.

oh, my bad, you definitely need a need to get that right before you even think of turbocharging

ok thanks for the advice, do you know if the tt engine is just a drop in easy to mount assembly? does it conect fine to the automatic transmission?

There are threads out there. Use the search feature and read, read, read.

flashable would be the smartest choice, you can get the ecu and an adapter harness and be ready,

dont worry about compression, just learn to tune, or get it tuned by somebody who know's what they are doing and compression wont be a problem,
and you'll probably still need to hotwire your fuel pump because your car wont support the two stage setup and you'll need to do manual boost control since you dont have anywhere in the wiring harness for the boost solenoid

so thats

flashable ecu
adapter harness
hotwire fuel pump
manual boost controller

then either you need a tactrix cable and a wideband to tune it or find a tuner with that equipment

i may be forgetting something but thats all i can think of for now

when you say adapter harness your not talking about a whole engine harness are you? and where could I find one these for this car? also insdtead of hotworing the fuel pump couldn't I just use the fuel pump from a vr4?

You really need to pick a subject that you are asking about, and search threads. There are many threads that will explain your questions thoroughly.

Repeating all this info as you ask is not exactly the most productive way to learn, or teach for that manner. Someone has already givin you a starting point by searching the tt conversion threads, and the chrome thread, You have not taken the time to do this, or your last questions would not have been asked.

Search, read, learn, ask along the way. It is all here.
