Thanks a lot for the replies!
Robert,
There was a guy over here using Racelogic with success. He changed for a Motec computer and used the inbuilt traction control. He said they were both similarly effective. A Procharger with a carb sounds cool!
Make sure if you buy the Motec through your friend that you get both the access codes for the unit. Without the codes, you just have a pretty little box to hang behind your bar at home...
Mike - thanks for the K-Type info. I just assumed that they were super fast judging by how thin they were.... My stupidity astounds me sometimes
I'd love to bring the G-Force trans back, but I'm still trying to justify the $5000+ required. I'll let you know well before the event if I'm seriously looking like getting one.
Richard - Yet again you've pointed out what i should have already considered.... An electronic boost control would work equally effectively on a supercharged motor. In fact, Motec have this as a standard Output function within the setup options! I was previously considering a fly by wire throttle system but gave up after realising how much trial and error is required to really use this facility to anywhere near it's true capacity. I fear if I just try to half do the job I'll simply add another potential reliability weak link into the system. I'll use the four wheel sensors in any case.
coyled and DV - My main fear is having an injector clog and ulitmately melting a piston. In this case, a wideband sensor or thermocouple for EGT will be reading FOUR cylinders, so the wideband compensation will only serve to richen the other three cylinders. I figure if that's the case, I'll still hurt that lean cylinder. If I install all eight thermocouples (the quick reading ones) into each cylinder, just out of the cylinder head I'll have a dead-on accurate indication of the true health of each cylinder. Datalogging can then show up any individual rich or lean cylinders and the laptop can make the corrections. If I never check the datalogging, the information is useless as a preventitive (bad injector scenario) measure. Hopefully the Motec will allow a warning light or buzzer to activate if any single EGT reads higher than a nominated figure. This way I'll have a real time, accurate indication that one cylinder is struggling.
coyled - I'm interested in the way that you've set up your Speed Pro. I may be wrong, but I thought most cars have the wide band set to work at UP TO 80% throttle position, then went open loop to the pre-determined settings based on load, rpm and TPS as shown on an engine dyno. This way, the closed loop wide band was used mainly for emissions compliance, low speed driveability and idle quality. Obviously not the way you're doing it, but have you also heard of this being the case? I'm also using a supercharger, so does this negate the airspeed effects of a naturally aspirated motor? Assumptions again, but by tuning the motor using TPS/Revs/MAP sensor and air temp, is road speed relevant anymore? I really hope you're going to the Fling, because I've read a lot about your cup-motored monster and I'd love to see it in the flesh
