Decided to go a different route, it's a complete ECU with the MAPDaddy 4 bar map sensor built in and it is the older style that requires splicing the MS harness to the stock harness if you plan to use the stock g63t engine harness. Never been installed and built about 4 years ago by Don(wite96gs).
$400 shipped



Thanks

You may want to lower that price since you can get that kit new for $333 here: http://www.diyautotune.com/catalog/ms230k-kit-with-mapdaddy4-upgrade-p-513.html

Granted, some assembly is required, but still I think your price is a little high.

Price is fair, because a assembled MS ECU is $432,

I understand the kits are cheaper, but they are that way because you need to assemble the unit and not everyone has the skills to assemble them. In this case this ECU is already built up and specifically for the 4g63.

I'll drop it to $300, because you can send into to Symtech to get reconfigured for the 420A for $40.
