Hey guys,

I am sure this has been answered but i cant seem to find what I am looking for.

I am going to NOT buy another Renny motor for my 8. Rather a 2.0 FE3 until the 16x comes out when ever that is.

SO when doing engine swaps i have heard of people running both ECU's, continuing to run the 8's ECU to utilize the cluster. In doing this could i get away with running a plug and play stand alone like the Haltec then re mapping it for the new engine? I want to utilize as many RX8 sensors as possible like the TB. I have done many swaps before but nothing that would requite this much wiring.

Would it be easier to get a stand alone run the new engine off of that, and splice the sensors needed to work the cluster and leave the 8's ECU intact?

Any thoughts help is more than welcome.

*Reason for the swap I can do the entire thing for less than the cost of a wholesale reman, and i have enough parts around to boost the crap out of it and make close to 400whp out of it. and it will be reliable which is a +

 

You should follow this thread on the rx7 club. http://www.rx7club.com/showthread.php?t=962639

I don't know enough about the differences between all of the standalones out there to recommend one. I know you'll need one that supports canbus to use the stock cluster and ignition and that's about it.

 

The cluster needs to be sent the proper CAN PIDs, there is no standard, they are make/model specific. Fastdruid has them worked out:

As does paimon soror.

However, I'm not aware of any device which will bridge a standalone and the instrument cluster gateway in an elegant manner. It could be done, but I think keeping the stock ecu running is the simplest way, albeit inelegant and irksome.

 

MoTeC .....

 

That or use a Haltech P1000 and their new IQ3 display dash.

 

Thanks guys great info to start.
