Hey everyone. So, my plans have changed yet again and I picked up an ej20k bottom end with ej20h heads that have been converted to run single Turbo. Here's the plan. I will swap over my ej25d intake manifold onto the 20h heads, and use the ej25d ecu to run it (for obd2 compliance). My question is regarding EM. Will a simple AEM F/IC unit do the job? Or an e-manage ultimate? I've heard success and failure stories on both accounts and my tuner hates the emanage. He suggested the FIC as an alternative but would rather see a link system in there (I'm not prepared to drop that sort of money on a standalone and lose obd2 in the process). If anyone has some real world experience with piggyback units I'd love to hear about it. To be clear, this swap is going to be conservatively tuned and wont make a ton of power until the transmission swap happens, which is another reason I will run the 25d ecu; to control the transmission. Thanks in advance!
