Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
Hello Grant,
Flashed one of my other capricious car with your firmware and again, THANKS !!!
This car had always starting issue when it was hot under the bonnet.
It is using all the oem component and there is no problem for hot starting with original ecu.
I always had to idle at +-13AFR, 13.5 (normal opération) at the max to allow easy start and idle (15-15.5 AFR hot restart) after 15-20 minutes for the first 1 or 2 minutes.
I did put a fuel temp sensor and found that E85 was hot only for a few second only so I assume it is not the problem.
Air temps sensor is an open element in sort of plastic epoxy before throttle plate in the air flow.
ASE help a lot but sometimes when fast hot restart happen with same air temp, it gives fuel when not needed. It must be related to temp of the intake parts, manifold, cylinder head, injectors coils temp maybe ?
I don't know how the OEM are dealing with this, but they seems to have a sort of ASE too and maybe they are ignoring the air temp correction or disabling it during hot restart ?
Do you think it could help to have this option in the MS2 ? It happens at a temp of 50°C or more, but since the car is turbocharged with a small intercooler, I can't use MAT correction table to fix it or it will add fuel when boosting and temp is going 50/60°C at the max.
Anyway, the idle code works very well, because before with hot start, the idle was hunting so much in a loop, now it continues to run without diying. I even could have a normal operation at 14.5-14.6 AFR and hot restart @ 16.5-17AFR with only some minor difficulties.

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
The idle target is that way because I wan't to keep my idle oil pressure high when the engine gets really hot. Normal temp operating temp is 80-90C and then the ilde oil pressure is 2+bar@950rpm but when the engine gets over 100C example at track the idle oil pressure drops down to 1-1.5bar so a bit higher rpm will keep the pressure up. Even with 10W-60 oil. So it's just a safety feature.gslender wrote:Watch status4 as it will tell you when DP is being added (it should be 34 - which is PWMIDLE_RESET_JUSTLIFTED + PWMIDLE_RESET_DPADDED) and 16 when waiting for PID to take effect (PWMIDLE_RESET_CALCNEWTARG).Perkele wrote: Only one thing I don't seem to fully understand is the dashpot decay.
My dashpot adder is 4.3% and decay is 10 and I'm using the IVT table.
But it doesn't seem to work as planned as you can see in the picture, it does add the dashpot adder but it drops back to IVT value right after. And most of the time it doesn't add the adder att all.
I've also seen that you have targ rpm clt curve that is 950rpm when 90deg and then 1200rpm when 100 deg ???? wtf !!

You mean something like "if MAT > x degrees F, taper in ASE over x cycles"? Or "if MAT >x degrees F, disable ASE"?

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
I didn't think you needed to worry about oil pressure when at idle - normally the issue for oil pressure is when under high boost/load (which tends to force oil out of the bearings and journals) - and is why oil under high pressure is needed at those times. But hey, if you want to have a higher idle when hotter - fine.Perkele wrote:I wan't to keep my idle oil pressure high when the engine gets really hot.

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
But back to my original question so when status4 goes to 34 I should see IVT value + adder decaying to IVT?gslender wrote:Watch status4 as it will tell you when DP is being added (it should be 34 - which is PWMIDLE_RESET_JUSTLIFTED + PWMIDLE_RESET_DPADDED) and 16 when waiting for PID to take effect (PWMIDLE_RESET_CALCNEWTARG).
G
This picture is from the log I posted on my question and on the current position IVT is 27.7% and adder is 4.3% so should it jump to 32% when status4 goes 34?
Is some of my settings wrong or what is preventing the adder to be added? Or is my understading wrong?
Thanks again.

Do you keep the idle valve open during acceleration?

Yes I actually do. I have noticed that the transition from idle to drive and back goes smoother like this.Greg G wrote:Do you keep the idle valve open during acceleration?

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
I replumbed my MAP sampling setup, added a filter in meatspace in the form of a ~1L "catch can" that runs off the plenum and acts as a condensate trap for my PCV system, ~14"x3/8" line connecting.
(preexisting setup, just was sampling direct to plenum, just rearranged a bit)
Was able to turn the MAP lags back to 100 and the squarewave weird accel/dcel triggering is gone, was also able to turn my thresholds back down on MAP accels from 400 to ~150 ish where they work again.

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
Probably. There is a zip file called "ms2extra_alpha_330b_gslender_v2.4.4.zip" that contains s19 files for Megasquirt2 and Microsquirt2.nismoautoxr wrote:Im trying to download the mod but there doesnt seem to be any firmware in the link that says firmware...am I doing it wrong
Download the PDF (gslender.mod.application_notes.pdf) and read them, it explains what to do to install the firmware.

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
pardon my PC incompetence LOL. So if I understand correctly ...I just go to my 3.3.0b folder and delete the 2 S19 files and paste the one from this thread into that folder ....?

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
Now that firmware is absolutely impressive . It is absolutely fantastic !!!!. Im running with no lags whatsoever with 100% TPS dot AE / threshold of 5!!!!! with no ...absolutely no false AE triggers and the idle control is very near perfect with no tweaks to any of the settings as is .im attaching my MSQ for you to look over GSLENDER. That is stellar work guys .
Had a spot of trouble at first with the idle speed.It was caused by a mod I used to use for table switching on PE0(hardware switch ) . I originally used it for table switching and totally forgot it was still there untill I turned the feature on and PID was disabled since the toggle was still switched to ground LOL.

I'd suggest you check the Idle Adaptive Voltage Compensation - the values are relative to the battery baseline (which floats but hovers around the avg values). Voltage values should be -2,-1.5,-1,0,0,0
Also, I see you've set IVT for CLT - I tend to think it makes more sense for it to be MAT based as this is the thing that changes from cold to warm... and unless you believe the idle valve duty remains the same for all those CLT temps, then you'll need to change them.
You don't have Adaptive Idle Advance enabled - that truly delivers rock stable idle... and helps recover too. So play with that and read up in the various past docs I've released in the earlier builds.

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
G, I guess I dont have my head wrapped around the calculation formulas for IAVC. Why are the numbers in the negative? i see the affect but the numbers you ahve posted dont seem to get the job done for my car when the high blower and the AC fan comes on The idle starts out at around 900 then as I increase the fan speed the idle speed drops and it doesnt recover enough to reach the target idle speed. Should I increase the numbers in the negative or the positive ?
Also the load advance KPA is very sensitive as it tries to adapt then the KPA teeters above and below the KPA limit and causes the timing load advance to activate and deactivate. Its definitely goingt otake me some tinkering but there are definitely alot more tools in the box for it now !

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
Ignore my last post . It was late and I had several celebratory beers when I posted that . I see what you were saying G on hte IAVC and have it set up now ...a little differant than the example and its working even better . I ditched the load advance and wnet adaptive and that works much better for my setup with the AC on . Again very impressive improvements on the TPS dot smoothing as well as the idle controls .Im down to 2.5 TPS dot threshold on AE.
I guess its about time that I tackle learning my way around EAE next LOL. Im sure that is going ot be a treat but now with the absolutely noise free TPS dot that will be much easier than my first attempt.

Re: [FW MOD] ms2extra 3.3.0b gslender v2.4.4
getting ready to load this to address rpm and tps/map dot noise.
might even re-try the bosch isv idle stabilizer I wired in and dumped because the pid never held better stability than the bleeder bypass screws and adjustable throttle stop knob on my turbo itbs project.
Any thought of applying the idle pid control changes to the boost control?
