2 step on fuel injected cars

[Chris "drooze" Wertman]

It all depends on the ECU and how its doing it, there is no deficincey of doing it in an FI system.

Depending on how its being done I can see Jeff could be right, but with an aftermarket ECU you can do spark, fuel, or both. If you do both....or fuel I could see an issue, if the ECU is doing its job right I can see having an issue.

If youre not doing it through the ECU itself I have no idea......all kinds of potential hiccups come to mind.
