Although it is a bit odd, it is actually not an issue, because I can tune the Volumetric Efficiency Load Multiplier table through the rev range to get the correct AFRs. Would still be good to understand.

Hi, I am logging from my NC1 mx5 that is turbo'd. I have got the tune into a reasonable place running 7.5psi. I have noticed that the Load value is flat lining at about 1.4-1.41 absolute load, even though the MAF values are increasing. The load did not go over 1.416 even when I accidently put 18psi ...

I am guessing the 800ms seen is more a limitation of the logging with regards to the lower limit of log output and does not reflect what the ECU is using. Since I have things running reasonably well now and I am still seeing a 800ms flat line from time to time.

I think i am getting somewhere now, I have reverted back to the stock dead times and I am finding that the engine is lean now, which makes sense because the actual PW will not be long enough, so I thing it is a matter initially of dialing in the dead time. I will reach out the injector supplier and ...

Hi, I have fitted some 640cc injectors to my NC1 mx5 and I am trying to reconfigure the ECU for the injectors. I have read a heap of information on injector scaling and believe I am taking the right approach. The issue is, i can get the engine to start but then at idle the injector PW just goes to 8...

Hi, I have wired in my GM 3 bar MAP sensor today and just viewed the voltage and KPA in the dashboard, without the engine running and it looks to be working perfectly. I have 1.52v with is about 38kpa with the MAP multiplier for the stock MAP sensor. I have edited by tune and set the MAP multiplier ...
