I just bought a R Magic ECU for my '94. It is tuned to run at about 14psi. I am currently running a stock fuel system (aside from a Walbro 255 fuel pump). The question I have is, would I have to upgrade my injectors to run this ECU?

 

I run 12 PSI and my duty cycle is in the mid to high 80%. So at 14psi you might be cutting it close to maxing the injectors out.

 

The ECU has to be tuned for larger injectors. If the ECU was tuned for stock injectors, that's what you need to use. I'm assuming this is a rechipped ECU?

 

Here is the ECU in question. When I bought it from the parts importer company, they couldnt provide me with detailed info on it. I heard from one forum member that 14 psi is what these units run, but he wasnt sure. Anyone here know more about them?
