Hey guys, thanks in advance for the advice. I recently got the motor back in, and running after a 2 1/2 year build. It's an 88 GT convert. with a fairly beefy HCI swap and all the goodies to go with it. AFR 165 heads, custom cam thanks to Woody, and a Trickflow track heat intake. Over the weekend I put on a wideband and started logging with the laptop, and honestly not sure where to go from here. Nobody in the area will tune a SD car, and I've never tried it. It idles a little high (1200 RPM) and is a little rich cold, but under heavy loads/acceleration I'm getting massive lean spikes to where I don't feel like I should drive it. I've looked at a couple different standalone ECMs and considered doing a MAF conversion so that I can take it to get tuned, but need some advice on which way to go, and if its safe to drive as is (under 3500). I'm leaning to the Megasquirt PnP side of things, just because its supposed to work with SD. What do you all think?
