It's a tvr Tuscan running with crank and cam sensor. It was running perfectly in 720 sync but has been off the road while I did some work. There doesn't seem to be a consistent position for the cam sensor for some reason no matter how much adjustment I do taking it closer to the cam trigger or furth...

Hi Steve, yes its a not a great screen shot. Ive now got the logs from the garage laptop. From the log there, i didn't actually run the engine, that was purely cranking it. I had previously seen 720 sync when cranking. I think the variance in width of the cam tooth is due to the speed of cranking. I...

Im having trouble getting 720 sync. I have had the car running before in 720 sync mode but removed my cam cover and cover position sensor to replace a cam cover gasket. Upon replacement I can't seem to get 720 sync. I have put the cam position sensor back in the same position and I'm I can see from ...

Hi Steve, Yes it's a wideband ntk sensor. When I looked at the gauge I was under the impression it was displaying volts. Between 0 and 5 which correlate to afr. AFR = (voltage x 2) +10 Am I mis-interpreting this. Definitely taking it to be mapped as soon as poss but just want to ensure there's no re...

Still can't quite figure out the rich running. I'm still getting a wide band voltage of 0.75 volts. The engine effectively only has an air temp sensor, a coolant sensor, throttle position and the wideband. All of the temp sensors seem to have decent values. The engine is lumpy from cold, and I have ...

Hi Steve, have got the car up to temperature, everything runs as expected. All sensors are working, fans cut in perfectly, throttle bodies have been balanced and idle is good. I have driven the car a couple of miles thats when I noticed it was running on the rich side at low rpm. I have used the man...

Thanks Steve. The car is all up and running now. Yeeeeha I think is running rich though on the base map I have, has a lambda/wideband O2 voltage of .79 ish at idle going up to .9 at 3k ish. It's also slightly lumpy at cold idle so I think I just need to get it mapped now. The only conundrum is I'm e...

Thanks Steve.

I'm planning on fitting the Bluetooth module for cal switching but not immediately.

Under cal switching in scal I can't seem to find a way of changing the cal I'm on. Presumably I'm looking in the wrong place.

Update.... After pulling the loom apart I discovered the ignition module had been wired back to front. Have sorted that and I can spark on demand with the output test :) Next problem.. When I first run the car up I'll need to balance the throttle bodies as they've been off the head. To do that I'll ...

Will check tonight Tim and post back.
