So my math was wrong. I did some tests, and cranking is much better, but still can use some improvement.

Cold start is ok, it's similar to what the DME wanted (in this case, 50 ms of fuel, I got 50 ms out of the value of 255 in the cranking fuel table...). 0.9 sec start time.

Mid temp restart ~100 degrees ECT was ok, but took .1 second longer to crank then cold.

Higher temp restart ~174 degrees ECT was good. 0.6 seconds total. Still longer then DME, but not going to complain.

Going to adjust numbers a bit and try again tomorrow.

what values for IPW are you seeing in the Proefi logs? 5000 or 50,000?

See attached.

Note the DME log isn't exactly right - I had FlexFuel enabled on the first cranking try, and it didn't even attempt to really crank - IPW on the ProEFI side was 1.08 ms. (1081.54 logged).

I turned off FlexFuel and retried. That's what is shown in the ProEFI log.

Oddly, with FlexFuel on, it cranks at anything > cold temp without an issue. Maybe I should get a flex fuel sensor instead of making it fault out.

About to look over what my changes netted out.

What injector angle are you using at startup? Try 575 BTDC. I had cold start problems with the injector angle set at 400 BTDC but now my cold / hot start times are better than stock. (Vipec)

Cranking start of injection is 0. But I've seen it at 0 on all the calibrations I've looked at so far... Value range is 0 - 920. I will try 575 and see how that goes...

Thanks!

This seemed to help a bit. Still not as fast as stock, but still completely reasonable - 1 second from completely cold @ 23 degrees F. It also sounds more like normal, not like it's going to crank forever...

I have also updated some scaling values for ECT that make it closer to reality.

I also realized that there is an offset necessary for the MAF voltage, which I will be testing out tomorrow.

Getting closer...

how did you calc your SOI values from BTDC?

Who is this question to? I just took the advice of zek926..


On another note, I noticed the reported values for mass air flow were slightly different vs DME, and I'm working on getting that aligned (there is an ADC offset that can be applied - not touching the curve itself.), then going to re-visit IAT and Injector offset curves. With Mass air, it works fine, if I try and switch it to MAP (just for testing purposes), if the car is already started, it's fine. I have the VE in the idle area fine.

However, if I restart the car, it fires, goes to about 1200, then as it comes down...it just never stops, and dies.

Fun stuff.

Still waiting on 3zz.

i ask because the SOI injection values that Proefi uses for injector phasing, are not BTDC as far as I can tell.

Ah. I didn't touch injector phasing.

In the cranking tab, I changed the Cranking Start of Injection values from 0 to 575 for 35-175 RPM.

right, thats injector phasing. do you know your cam profile to know when your valves are open/closing? and if that value is not BTDC, do you really have any idea where in the valve position your are spraying your fuel?

I dont know where the TDC is the firing angle calculated from, so I was hoping you knew.

Jason just said its based on #1 compression. #'s like 575 would usually indicate EOI like how Haltech does it. Proefi uses SOI. need to find a cam/crank card to figure intake valve position....

So I realized the VE table was set up for Alpha-N, not MAP. That's what was causing the weirdness.

My attempt at re-doing the injector curves was not good, and I put it back to the way it was. It was fairly close, and better then my attempt from the Racetronix data Nick sent me.

I tried another shot at the DeltaTPS tables, failed horribly, reverted that too.

I did clean up the IAT curve, left that in place.

I finally got Decel Shutoff to work - the value in the UI is the MAXIMUM reading for MAP for Decel shutoff to work. So, 0 means it'll never turn on... Set it to around 20 and it will do the right thing..

I also got my O2FailedRich and O2FailedLean code to go away most of the time, there are some settings in the O2 setup that I missed earlier...

Still no v3 from Jason. Losing patience.

So, mixed bag - getting things better, but, still no torque reduction, which makes for an annoying experience if you don't actively work during the shifts.

Worst case scenario I will drive down to FL and have Nick do a calibration for stage 2 and call it a day. E85 is awesome, but a pain in the butt at the same time.

which O2 settings helped with O2Failed codes?

Lean / Rich EQ Target Delta changed from 0.00 to 0.01
Lean / Rich EQ Switch Pt changed from 0.00 to 0.02

That seems to have helped for most of the time. Idle is a little stupid..

Finally.

I have in my possession, the 3zz_S54 firmware for Digital 60-2 Crank and Variable Digital Half-Moon Cam. It took some back-and-forth emails directly to Jason, but it happened, and to be fair, within about an hour once he said he'd do it. Just frustrating to not be understood as to what I need.

That all being said, I will install this later tonight, do some testing and see where I am.

Yesterday's build of the firmware didn't work.

Trying again with a new build now.
