Cant you just set a higher threashold for TPS or MAP?

I get why tpsdot would be a good idea.

James was that directed at me, on the AC feature? If so just where is the "Loop" feature at?

Do you guys think this is usable (semi-reliable) on a road car at the moment?
(im currently on 1.4.1)

Development seems to have halted for quite some time, and i would really like to get 128-byte logs working.

I've done a couple track days with it and very few bugs mentioned these days so I think all code pretty stable.

Take your laptop with you to re flash for first few drives?
That's what we did in the old days.

I've been driving with it daily for a few months, not a single issue.

Hi, I'm bench testing this firmware and noticed my ADC11 (Ext_Map) displays it's value sporadically (In tunerstudios and logging). I have my oil pressure gauge hooked up to it and set as a generic sensor. The value that is displays is correct, but it displays every 1-5 seconds randomly. I just did a clean install as-well, same results.

Drop down to 1.4.1 and it works fine. Also tested the MCU and the correct pin sees a constant voltage with my DMM.

I think there was some debug code remaining that was overwriting those values. Should be ok in the next alpha.

Excellent. Glad it wasn't my engine, then sensor, then ms board. lol. ADC 12 & 13 seem to work as expected.

Throttle Control (DBW) feature

Post by jsiedlicki »

Is there any documentation for the new Throttle Control (DBW) feature in this firmware? I am very interested in testing this in the 1.5 firmware.

Is there a roadmap for the features coming in 1.5 or has it been pretty much tied off and waiting feedback for bugs? Curious..

I know there's been a bit of a hiatus due to other projects. There is new code to in-progress, hopefully within the next month or so.

Didnt want to start a new thread so this will do.

James.... did you mean to pin the "MS3 pre-1.4.2 beta 1 released" thread instead of locking it?

Substantial changes to 1.5?
I'm wondering if i should still try this 1.5 alpha, or now wait until the next release.
Not much point using this version if there are substantial changes coming.

I was using this firmware and my coil outputs went from melting a coil to no 5V output at all. Went to 1.4.1 and it fixed the problem.

It has been a while since updated, stable, firmware has been released. Just wondering when/if 1.5.0 is planned on being released?

First run around on 1.5a4 went ok. Drove like nothing had changed.
No transition issues other than having to set that 29bit CAN format switch, and editing the INI for 128byte logs.

The first issue i have noticed is that now VSS1 and VSS1ms are being logged as 0.
VSS sensing options have not changed from 1.4.1 to 1.5a4.
My digital dash speedo (read from the MS via canbus) was working OK, so this must just be a logging issue?

[edit]
Hmm, looks like a quite few logged items are reading 0.
AFR, AFR error, Boost target 1, Ethanol percentage, and more...
