I picked up a set of new 850cc injectors from the RX7 store & had them forwarded to RC Engineering converting them to 1300's.

My question concerns lag times & proper 1300cc secondary injector set up.

From my reading through old post about 1300cc lag times I came up with anywhere from +.16ms to +.43ms, with the understanding that +.2ms works well.

The 1300cc correction value would be 65%

So on the commander "injector pulse timing correction" screen do I want to see the following????????????????

Fr-Pr 100% +0.00ms
Fr-Sc +0.20ms

Rr-Pr 65% +0.00ms
Rr-Sc +0.20ms

Q-Pr 550cc
Q-Sc 1300cc

Thanks,

You need to change your rear primary to 100%. The 1300's don't have anything to do with the primary numbers. I'm also running .20 on my 1300's.

 

I was under the impression that while the commander display shows the front & rear primary & secondary injectors separately, it's really only broken down into Primary (FR-Pr top reading %) & Secondary as (Rr-Pr bottom %)

Since there are only two adjustable values. The example in the manual is confusing at best.

From the couple of replies I've read, it appears IM wrong.

So all I need to do is change the Secondary lag times to + 0.20 & leave both values at 100%?

I still input 1300 for Q-Sc correct?

Thanks for the clarification.....
