Re: negative knock retard
Under normal driving circumstances none of these values is dangerous in any way. You would have to worry if you saw more than 2-2.5 degrees of KR at high RPM (4500-5000+) and high throttle application (WOT) on a turbo vehicle, or more than like 5 on a NA. That "knock retard" parameter in t...

Re: Help, guidance and advice please (2.3 engine swap mx5)
as in what tables are and how they work together, what's the ideal rates depending on usage, how to recognise safe limits etc? The factory turbo can barely push the engine towards the "safe limits" if the boost control system is in factory configuration. I could try to help you with the t...

Re: Help, guidance and advice please (2.3 engine swap mx5)
LTFT 25+% - assuming there's no obvious leak I'd say that intake needs a calibration. Versatuner will only give you access to the ECU, no other modules. I guess you can access the other modules with forscan or a similar tool and see what can be done from there. The TSC switch on the CX7 will only di...

Re: Mx5 NC1 1.8 Manual Idle Issue.
So fuel trims are fuel trims, these are deviations between what the ECU expects and what it gets. Idling for 20 minutes doesn't reset anything. Keeping the engine at 3k rpm doesn't reset anything. I have no idea where this procedure came from. Doing all this just warms things up and if you have one ...

Re: Mx5 NC1 1.8 Manual Idle Issue.
Since it's an NC there's a change that the rubber/silicone o-rings between the intake manifold and head are crusty and not sealing any more. So you may want to take a look at that, because the symptoms and the inconsistency of how they appear (usually for vibration/heat related reasons, which is har...

Re: Mx5 NC1 1.8 Manual Idle Issue.
Ok, so you have a huge vacuum leak, it can be anywhere after the MAF and the head (including the intake manifold gasket). You need to check everything in that area.

Re: Mx5 NC1 1.8 Manual Idle Issue.
I'll see if I can record a good log on the way in to work tomorrow (roughly 20 min drive) I don't know if that will be too long? Only catch the problem in that log. If it can be reproduced then start logging before triggering the problem, trigger it, stop logging 4-5-10 seconds later. If you take a...

Re: Mx5 NC1 1.8 Manual Idle Issue.
Can you please take a log when that happens? Make sure you log both short and long term fuel trims, engine RPM, timing advance, throttle position, and if you have available on the platform also the desired throttle position. I assume this issue is not present with the factory tune, right? What about...

Re: Desired AFR
As far as I can see you leaned out the factory MAF calibration for some reason, so the desired always sits around stoich because the ECU reads lean continuously because of the significantly leaner MAF cal (about 10%). You did not log load in your log, but by looking at the tune and the log you never...
