Monopony! Byrons last message...."Car arrived with 70 PSI of base fuel pressure,erratic idleand running poorly.
Before first pull, fuel was set to 39psi vacuum off. Built first calibration with 28deg total in chipand 12.7:1 commanded AFR. First pull netted extremely poor numbers and was aborted early due to weird retarded exhaust tone and lack of power, which made us check base timing because it could not have been at 10 deg BTDC.
Base timing was at 8degATC...18 deg retarded from 10 degBTC; 20 deg retarded from 14deg BTDC if that's where the customer thought it was.
Timing was set to 10deg BTC base.Next pull, car ran correctly.
Timing was advanced until edge of detoation and backed off 2deg BTDC in chip. Totaal advance(if I remember correctly) was 30degBTDC in chip final. This will be 2-4 deg less thanwhat non-california folks will advise; due to our fuel. 28-32 is normal, dependingon the combo.
AFR was tuned to 12.9:1 Car made something like 260ft/240 hp at the rear wheels. Not terrible considering that it's an AODE with a stall converter. All pulls were done in 3rd with the torque converter locked.
I also entirely remapped all of his AODE shift points and torque converter lockup behavior for optimum performance and drivability, both up and down shifts.
He stated something about 14s 1/4 mile times previously. I'm suprised it even did that. It must drive a hell of a lot betternow..and what ET's? Who knows; It's hard to judge with AODE cars; I don't see enough of them. I'd hope he'd be low 14,s but with a heavy car(3500-3600) and an automatic,it's going to be hard to hit 13's without a power adder.
He also has a torque converter that pulls real hard at 800rpm even though it's a 2600-2800 stall. It shouldn't...but it does. It pulls enough that the carwants to stall when going from neutral to drive, or neutral to reverse. With a cam, you need a converter that doesn't load the engine in the idle range..this one does.
