No Purring here..
(Just kidding. Wish you lived close so I could take you for a spin.)
They really run just like a stock Supra with a big single turbo setup if you follow the tested path and maybe even if you don't ultimately, as our few 97+ guys have proven.

yeah the safc works on both maf and map cars it just scales the voltage, so it works on usdm ecus or jdm ecu's doesn't matter.
what it cannot do it convert from a map sensor for a maf based ecu, thats what the vpc was made to do run a map on a maf ecu.
no one converts a maf signal to a map based ecu cause well you would just use a map sensor already on a map ecu so there is no device for that conversion.
I think 660's it the normal max for the jdm ecu, people run larger but you will probably take a little driveability hit. if you are thinking 1000cc on pump gas then its standalone time.

on the 1zz aka "internally ignited" coils you do not need a seperate ignitor. With 2jzgte coils you need a 6 channel ignitor (GTe one not the ds62/dh61 3-channel for vvti coils)
The difference in wiring is each one needs power and each one needs ground.
Each one also puts out its own IGF, so you must connect all 6 IGF wires together to the stock IGF wire.
Then it will fire up and run properly.

Hate ask a redundant question, but I can effectively delete the wiring going to the igniter, yes? And run the coils directly to the ecu, the igniter no longer serves a purpose.

Lol, no Ali, I simply took the original spark plug cover flipped it upside down, trimmed some of the metal on it, and then welded mounts for the coils. Pretty happy with how it turned out.
Again thanks removing all the non essentials from my wiring harness it's really simplifying everything.

studiogeek. Map ecu3 is a great piggyback if your power goals are under 800. highest map ecu car made 962 or so on e85. So you have nothing to worry about. And 1000cc can be done with aristo ecu. idle and cruising tune are the sensitive parts. I agree with the fact that you are going with 550cc. You can get close to 500 on those injectors. And tuning them with the map ecu 3 is not that bad as its only a 25 percent fuel change. If you can get a conservative tune with the 550, you will be happy. btw car is coming along. gl

The tt ecu mod is pretty straight forward just take it one step at a time, and remember, always practice common sense

Start making your spreadsheet with the things you know you will need already. Others will chime in on what else you need and help you decide what brands to get.
The routes vary wildly. You can't get a price until the important decisions are made on route and parts. That said, others can chime in on what they paid.
