Re: Miata NA 1990, 1.6L stock #21

Can you please post a picture of your MAP sensor and hose? Wonder how you've mounted it and where you do you take vacuum. The set up works with the previous Sept. 6 firmware. See logs posted above. MAP sensor is installed on the frankenso board and hose routed through firewall to a spare port at th...

Re: Miata NA 1990, 1.6L stock #21

Ok, I've been driving this car as my daily on the stock ecu for a couple of weeks. So I switched out to rusefi to what I previously had from about Sept. 6 firmware, and attached the log from that below, rus279.msl. After updating to 10/8 firmware I cannot start, and I get an unexpected MAP value err...

Re: Miata NA 1990, 1.6L stock #21

I tried closing up the frankenso case and grounding it to see if signals get any cleaner. And I drove for a longer test run and attached the logs. CLT and MAT values still look pretty noisy. But looking at vbatt, it looks like its noise or modulation is getting amplified in the values that CLT and M...

Re: Miata NA 1990, 1.6L stock #21

What is needed to get the other data values logged? Is that an ini change? My frankenso board is in a case, but is open and not bolted down. I'll try grounding the case and look at the signals more. I have the stock AFM with temp sensor in place for MAT. I guess the MAF is recording AFM signal, but ...

Here is my tune. I started with an old one from @thommm and have tried to tweak and adjust using TS Tune analyze.

Need to set coverity to ignore usb_msd.c and that "register struct intctx *r13 asm ("r13");" issue if anyone wants to figure how that's done. I have not tried this, but looks like you can ignore by file, type or specific issue, explained here: https://ondemand.coverity.com/help/...

Re: Miata NA 1990, 1.6L stock #21

How did you trigger this? I see a big difference in injector duty cycle if you compare before the miss and after, how did you get this scenario? From driving I could tell there were problems when accelerating from a stop, shifting through gears, reving up to 5000 or 6000 rpm, and also when accelera...

Re: Miata NA 1990, 1.6L stock #21

Looking at the saved traces, I found other odd case. After an inj miss, the other injector has an odd cycle and overlaps with the first.

Re: Miata NA 1990, 1.6L stock #21

I did more testing and gathered some data with a logic analyzer. Idle is smooth, cruising is smooth. Shifting through gears is rough with miss/hesitations, and accelerating from 60mph to 70mph in 5th gear is rough also. I gathered samples from the analyzer while driving (with the assistance of my so...

It looks like a miss can occur when their is large change in MAP value, which corresponds to a large change ...

Thanks, Russian. This new version does capture when misses happen! I drove a couple miles and tried to watch TS gauges monitoring the warn count.
