Im a little confused with tunning the timing. I get the whole knock thing but when your dynoing your car You use an EGT to tune the timing right, along with watching the tq curve? Is there any specific egt your shooting for with the honda engines. Ive seen these nifty clear sparkplug type things that change color according to your a/f ratio inside the combustiion chamber, and you can somehow determine whether you need to retard or advance. Anyone know how to do it exactly? Assuming you have a basemap modified with a step retard for boost already.Just looking for some fine tunning without going to the dyno by using the EGT actually.(Might not be worth it but i just wanna make sure im running in the right range.) Ive got a H22a1. Vtec engages at like 4300rpm and it pull hard right after that then it sort of feels like it looses a little right around 6k rpm then picks back up all the way to 8k. I have a A/F ratio of 12:1 through out the whole pull, i just htink i might have retarded a little bit to much or the basemap i was using was a little retarded out of the whole.
Thanks

I'm assuming you're h22 is boosted by the "step retard on the basemap" statement...if this is true, try gapping down your plugs a hair and try that.
