I dyno'd my DOHC ZC on a stock PM7 with just an exhaust. This is what the AFR vs rpm looked like:



As you can see, the stock tune is garbage. My oxygen sensor has sorted this out for daily driving, but now with a DC spot header the o2 sensor isnt getting heated properly (or is that the issue?) and thus not correcting for said garbage tune. I'll be crusing at ~5% throttle, then go to give it a little more and it takes a second to catch up. Same thing happened when I unplugged my o2 sensor. Now, I've been going over my options for either fixing the o2 problem or using a chipped PM6 I have access to. Heres what I'm thinking:

1. Buy wideband o2 and use the 0-1v feature to feed the ECU, eliminating shitty daily driving

2. See if I can't rig up some sort of temp controling circut for the 4 wire o2 sensor I have laying around

3. Buy an obd0 VTEC ecu and disable the VTEC - allowing me to run BRE and the sweet autotune function. A friend of mine did this on his type r and its tuned perfectly.

4. Try my hand at turboedit. I've tried this before with the chipped PM6, but I can't get a PM7 map to correctly import to the modifiable one. I'd have to buy a wideband o2 sensor and borrow a friends controler.

This is my DD, so I can't do anything crazy with it unfortunatly. I hesitate to go with turboedit because I can only assume that the timing maps import incorrectly as well. Suggestions?
