Stuart - I had thought of your car right off the bat and spoke to Kyle Jr. this morning. While he didn't have the solution (we're using different harnesses) he did at least give me an alternative.

I think that I have calls into just about everybody who could possibly have been involved in either of the products... hopefully I can get it sorted out today so it doesn't throw us behind... time is getting tight.

Thanks again,
James

James keep us posted.This is intresting. What kind of harness you are useing ? And is Stuart running Speartech ? Anybody with latest GMs own controller / harness ?

Yeah it gets pretty confusing at the track with 5 Roger or Rodgers in our pit.

Five of you? In the same place... wow... you're confusing enough on your own.

I will let you know how this plays out. I MAY have found a solution through Racepak - they are going to overnight an adapter that they think should work. At this point I am cautiously optimistic but part of me will still dread opening the box tomorrow morning...

I am running MSD's stand alone MEFI harness and ECU. From what I was told this morning, Stuart is running a stock (based?) harness and reflashed ECU.

From what I have heard this morning, the way that some people are using the Racepak dash in LSx applications is the same way that you would with a non-EFI engine - with what would amount to a second set of sensors and Racepak's V-net CAN bus cable. That is always an option (and is our fallback if need be) but the way that it has been explained to me the loggers are supposed to interact with the ECU harness directly as the MSD harness (and maybe the factory one as well - I can not speak directly to that) utilize CAN bus architecture.

Hopefully I will have an update in the morning.

Thanks for looking; I've posted there a couple of times over the past six months (I think that all of the MEFI4 questions are mine).

I think that I have got the the right person at Racepak now and it does look like there might be an off the shelf solution for this (fingers crossed) which, if it does work, will represent a great opportunity (for the next guy who plans to do this). UPS willing I should know for sure tomorrow.

Thanks again everybody,
James

James,if you are talking with the racepak , can you ask is there any chance to get "plug in" system for GMs own harness ??

Racepak was really helpful and overnighted an adapter that plugs directly into the MEFI4's harness and the IQ3's V-net cable. After some programming of the dash, we should be able to monitor and record all of the EFI's output channels on the dash.

So, crisis 1 is dealt with, now on the the programming...

Thanks to everybody who helped out with this, I appreciate it.
