ecu modding

Pretty sure what he means is "ALL 98,99 ECU's are flashable. Doesn't matter if they're tt or na. And anything older is not flashable."

sorry still confused, I get what several people are saying how only every model is flasable between 98 - 99 but then one of the last guys told that any sl could be programaed to be like a vr4 ecu.

so does that mean I can program my 97 sl ecu then?

You are definitely confused. Only 98-99 SL and VR4 ECU's can be flashed.

NO.

Only 98 an 99 dohc ecu's are flashable.

Do a search for "chromed". Read all of that thread

From the phone.

Dude, just take stealthee's word for it, lol. Don't worry about what one person may have said. Your 97 sl ecu cannot be flashed.

He misread my post saying people have turned SL ecus into VR4 ecu's as meaning any SL ecu can be turned into a VR4 ecu, not a 98-99 one.

Look, you are asking about ECU modding and adding turbo's, yet you are complaining of having compression issues. With your current amount of knowledge you have a TON of reading to do before you even consider a TT conversion.

I know I just like to plan ahead is all in a month or so I'm going to be getting my compression issues taken care of and then slowly start buying part for a turbo conversion. this is just me learning about it before hand.

anyways when I'm ready I guess I have to get a 98 vr4 ecu and plug it in then huh?

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

The compression I brought up has to do with his other active thread. Compression is down on his car so his car isn't even healthy right now.

[3000gttom]

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