my tuner thinks ID850s may be too much injector? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

My tuner says that ID850s may be too much injector at idle as the pulse width can only be backed off but so much. Considering how many people here use them...how could this be a problem? Any suggestions or words of wisdom to make my tuner feel better?

any issues so far? My tuner said he had a CTS-V in his shop once that was stuck with a rich idle due to the ID850s inability to dial back enough fuel. Why is it I have never hear one single complaint in any forum?

Did your tuner use the injector data provided by ID? Specifically did he correctly use the "Short Pulse Adder" table?

Stephen12ZL1 · 01-15-2013, 05:35 AM

he hasn't tried my car yet...just anticipating a problem...I will inform him about the short pulse adder table

ADM PERFORMANCE · 01-15-2013, 06:10 AM

No issues

Stephen12ZL1 · 01-15-2013, 08:19 AM

great...any special tricks with the tune to make the idle not so pig rich?

Alvin@PCMofNC · 01-15-2013, 08:38 AM

We've used them before also. They are really easy to dial in.

He is wrong.

And the "Injector Offset" table. Just as important. Three tables in all need tuning for an injector swap, as long as only the injectors are changed.
