The stock LT5 use 2 ECMs from the factory. A E99 and a S53 ECMs. The issue with the LT5 set up is fairly locked up and does not have the flexibility we want.

So would the direct injection be a MAF based system and the port injection speed density? I’ll bet it will be fun keeping the two systems stable and playing well with each other. Sorry for all the questions. Just find it interesting.

Thanks,
