ME221 2.0-RC30

Postby Alex@ME » Fri Jun 30, 2017 4:21 pm

Hi,

Biggest feature added is the ability to use analog inputs as switches.

Since RC25, the Ignition IAT and Ignition CLT trim tables are now additive. If uploading older maps, please double-check the values in these tables. Contact us if unsure on what the values should be.

Cheers!

Hi,

It says at the top, the addition of analog buttons + the changes from the previous versions. You can find those in the previous release thread.

Yes, it contains a fix that reduces the risk of bricking the ECU when saving to flash. The incidence ratio is quite low and the cause has been narrowed down to an issue in the processor's design. No reason to update unless you're running a brand new unit that you're going to tune.

Hi Alex,

i need a suggestion please: in september 2018 i went to a trackday with my '00 Mx5 NB 1.8 turbo with me221, wideband AEM, EGT, firmware 1.8.4 and a good map with AFR=10.9/11 at full boost (8psi, stock internals), which leads me to max 750/780°C in WOT in 4th ant 5th gear. Everything worked just fine. The egine did some other trackday with this config and it was sweet.

After that i just did an oil service (both engine and differential) and to improve cold start, i updated my ECU firmware to the 2.0-RC33. The car started really well with the setting prime on key on disabled. I just didin't test anything else, because the car was just running fine.

In october 20th 2018 i went to another trackday and the car immediately started running a lot lean in boost (something like 12!). I noticed that because my EGT went totally crazy (878° in 3rd). Boost was solid but i pitted to enrich my map with no result at all. The car just won't go under 12/11.9 which is too lean. Both gauges (EGT and AEM AFR) confirmed that the car was running lean (just to ensure that my EGT wasn't broken. The egt is mounted on the cast iron manifold, between 3rd and 4th cylinder at about 1.5 inch from the head). To continue the trackday i decided to creat cold spot on my map, where i enriched the mixture to cool down the engine.

Fuel pump runs great.

Now JUST TO BE SURE, could you please categorically exclude that the new firmware could cause a behaviour like that? So i investigate on something else...

Here's the first trackday where the car run so good

And here the secondo trackday where you can see my egt totally go over 800°C in a blink of an eye and the AFR is really high

Thanks a lot for the support,

cheers

Hi Gaetano,

Did you update to RC30 or RC33? RC33 has been running hundreds of cars fine, however, jumping from 1.8.4 to newer firmware is quite a big increase in features, tables and functionality so it is possible that some aspects of your old map aren't perfectly suitable to the new firmware. Also, it is possible that certain default settings of the newer features might not play nice with your hardware setup - hence getting a warning when loading back your old map.

As you can tell, we don't check the forum as often as we'd like, so could you please send us a log and calibration to support@motorsport-electronics.co.uk ?

Regards,
Alex

Hi Alex,

Thanks again for the support,

Hi,

My car started behave normally with the old firmware 1.8.4 so I think I'll keep that

Thanks for the support,

Cheers

Gaetano
