Default Custom Chip and injectors question

Hello

I have a small question. For the moment i have Accel 30lbs high impedance injectors with a custom chip burned for my injector size. What happens if I change to 55lbs low impedance injectors with the same chip that i have burned for 30lbs? Will it work? What happens?

thanks

regards

Tomas

You will run very rich because more fuel will be put out with each injector pulse.

I don't think that the low impedance injectors will work with the factory ECU (computer). The driver circuits in the stock ECU won't handle the load. Here's a discussion on the MSD site that might help. http://www.msdignition.com/
Go to the fuel management ECU compatibility section. :)
