Re: MAF Tuning or VE base tuning?
It has a VE table and another table for VVT VE adjustment, but since it's MAF based altering that VE table hardly makes any sense, possibly only for very aggressive cams.

Re: 4.5 BAR Map tuning
The 4.5BAR MAP sensor I had from CS needed 360/0.275 and the offset was 19.51. Did they change these values recently? The MAP sensor change has absolutely no connection with your VTCS error, unless you messed up something when you installed the MAP sensor. So you may need to check those big connecto...

Re: MX-5 NC1 1.8 gear ratios
It will not affect the speed displayed on the dash (or OBD, which is also the source input for the dash speedo which applies some multiplication factor for it) because that's read either from the gearbox final gear or from the ABS sensors. However, that data is in the tune because it is needed to ca...

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.
