Going from HKS SAFR to Chrome ECU

Well, after 15 years of using the HKS SAFR, looking to finally move over to Chrome. The SAFR was setup to manage 550cc injectors and just upgraded the turbos again and bumped to 720cc injectors. Car is running in the garage, but hates it when I blip the throttle and goes pig rich and dies. Adjustments on the SAFR don't seem to be assisting, so looking for some advice. The SAFR was wired a long time ago and can't seem to trace where all the connectors are. If I zero out the SAFR for now, would it be ok then to try Chrome on her?

Also, I would love some assistance. Would love to do a screenshare or Google hangout with some folks with Chrome experience while I try to get her running. Years ago we would have to do a gathering in person...now it's so easy to just conference everyone in!

Thanks!

Zeroing the safc out should work fine, though I thought the safc was an Apexi product, not hks. To set her up to idle fine, on a stock 99, all you do is input injector size and latencies into the chrome rom. There's a good guide on getting started on chrome on the "other" 3s site.
