What do I have to change to go from my MRE to a 6.1 chip? I know I had to put a 3 bar map sensor on the car and add a wire to the ecm but I forgot witch one and where it went on the plug. I'm trying to update my Buick.
Thanks
Chad

The 6.1 chip requires a powerlogger and wideband. It doesn't require a MAP sensor. You'll have to put a MAF back on.

Thanks Eric but, I made a mistake. I'm looking to go from a MER to your SD chip, a powerlogger and a wideband o2. I'm going to replace the body computer durning the swap but I remember changing a pin location on the factory plug for a 3 bar MAP. Is this going to effect anything on the new setup? What wideband do you suggest.
Thanks
Chad

You won't be using the ECM MAP input, the SD chip will get all it's inputs from the Powerlogger (MAP and wideband). PLX and AEM make good widebands. If using race fuel then I would use the NGK Powerdex.
Is this a race car, or street car?

My current setup is, 70 Bob turbo, 3000 stall lockup, 72 lb's with MER and a front mount. Looking to change injectors to new style 60's with your SD chip and a wideband with a power logger .
