st 204 turbo Options

[thorshammer]

Hi I have a st204 Celica with 5fse engine and am wanting o turbo it. I have read 1bwilson's and Shid's posts on turboing a 5sfe and list of components needed and this seems to be the best way to go. In my neck of the woods CT26 turbos are hard to come by, T3/T4 turbo is easier to sourc.e My question is what T3/T4 do I need and other than a CT26-T3/T4 adaptor is there anything else I need. I live in Australia so Mustangs and other American cars are not common here but plenty of Japanese sources. Thanks

Wow, is megasquirt only 12x12?? f**k that my power fc is 20x20 and i find that not enough.

also I find GT28* series turbos exhaust side too small, I made a huge mistake in choosing one. Would recommend GT3071R with the small option rear housing instead

The timing map is 12x12 and the fuel map is 16x16.
I honestly don't know what you need more resolution for as the entire thing interpolates between all of the table values to give you basically infinite resolution. 32x32 tables might sound great on paper, but good luck tuning 1,024 individual cells.

But if thats still not enough, you can trigger the table switching function in the ecu to give you 30 x 16 or 16 x 30 fuel tables and 12 x 22 or 22 x 12 spark tables by having the ecu use the dual map feature that ms2 has.

MS3 is 16x16 on both, too. I see that all the time, even on piggy backs like the AEM F/IC, where they boast a 20x17 table, I believe... but is it really that necessary? I mean, 12x12 in my case is more than enough. My tuner likes it that way and the car ran fine before the engine finally gave way after horrible years of abuse from a neglecting PO. The MS3 is 16x16 so if you're into larger numbers go ahead and get that (even though the main reason you should is because the MS3X outclasses most other ECUs in its neighborhood, considering feature:cost ratio)
