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...

Re: Speed 3 1st gen wont idle
Well, you need a MAF calibration for that intake. The engine will not stay running with such a big difference in air flow. Download the MAF calibration from here: https://corksport.com/support/instructi ... ration.txt and add it to your tune.

Re: Unable to Update
Probably it passed more than 1 year since your last update. Log into your account at versatuner.com, go to Versatuner -> Licenses and Downloads -> Versatuner Downloads, download Versatuner run that file to perform update. See if that works, it should. Once you do that you should be able to download ...

Re: ND1 Turbo with 3Bar MAP sensor has a limit around 5500rpm
Ok, and what tune are you using? Did you change any of the existing tunes, you're using an OTS tune, a custom tune made by somebody else? Can you post it here?

Re: Learn values
Every system has default calibrations. However, these things may have variations from the defaults which are more like a point of reference rather than a target. By example air flow. The same volume of air at a given temperature and atmospheric pressure will have a different weight (actual mass) at ...
