Is it possible to tune a 96 sc400 ecu? Been trying to find maps but all I can find is needing an additional aftermarket ecu. Hoping thats not the only way. Thanks for ur help

No you won't be able without replacing chips ... just wondering why you need to modify a stock sc400 ecu map ?

Running catless dont wanna see the cel and going to be adding bigger injectors and deleting egr. Dont know if the last one needs it but I know o2 code and inj need it correct?

a ems would be a great option. But support is limited for the sc4.

Yea I've been seeing that so is that the only option for an sc400?

This doesn't justify going aftermarket or a modified SC400 ECU even if there is someone who modifies the stock ecu for which I am not aware of.

Wanting to go catless and deleting the egr , I assume you are not required to go through regular emission or any gov't tests cause it will never pass even if you have a modified SC400 ECU or aftermarket one.

you go catless and deleting the egr will definitely throw a code not unless you trick the ECU with resistors pretending they still exist , if you dont want seeing the cel.. remove the bulb.

if you want bigger injectors .. install a piggy back. My next question is why do you want bigger injectors ? I assume more power ? there are other things you would want to consider and look into with your setup aside from just installing bigger injectors. You want the whole setup be reliable. You upgrade one part without taking into consideration the rest will eventually cause more harm than good.
