i just recently added turbo to my 420a, and i was looking for some type of computer upgrade, either a chip, or some kind of management system, just wondering what you guys are using, thanks
You only have a few options:
1. AFX ECU (I would not use this with a turbo if I were you)
2. Complete stand alone (good luck) If you try anything like this I would only reccomend the Megasquirt and if your asking this question then I don't think your ready for that yet.
3. Piggy backs SAFC, 8 inj setup, etc. (I would not use the SAFC to lean it out though)
