Hi Gents, anybody of you running ITB´s in the Z ? Have ditched the triple weber 45´s and setup up the jenveys with an aftermarket ECU and wideband lambda. My question is at what AFR are you aiming at idle / part throttle and WOT ? not sure at what the engine likes so far. Have tuned some honda K20´s with the wideband and had them until 50% throttle at 14.7 and then slowly to 13.0 at full WOT. Maybe somebdy can shed some light ?
Hi Folks, I finished a stout little engine build for a customer of mine here in South Florida. It's a 10:1, 40 over L28 with a decent cam. I assume I'll have to throw some more fuel at this engine but it's going into a stock 1976 280Z with the original fuel injection that was working fine. I have done many engines like this but never into a stock FI system. What is the preferred method of adding fuel? The less complicated the better! Thanks, Greg Ira RevTec
I am about to hook up my o2 sensor and start autotuning. I know the lean cruise around 2300 is rich. I plan on tuning that to what the car will tolerate. car is 77 280z n42/n47 stock. tune is based on gavins tune. I've been told the upper right section is accurate and ideal. I have no idea what to do on the lower left except for my idle 13.2 and cruise2300@55mph in 5th gear. aft.bmp
