new $EE tuning thing!

[steveo]

i dont quite understand what you're trying to do, do you have a push button 'switch' to enable your maf thing, and then the controls will send updates when changed? or do you want to have a 'send' button that when you click it it sends the updates once?

if you can't figure it out send me your source code and i'll play with it a bit

[kur4o]

The idea is to set cell number and maf value, than press the button once to send the command. The duration of the send command can be until the button is pushed or for a predefined time.

This will be for setting the ram maf table.

There will be another global enable switch that will make pcm switch between ram and rom table. It will be also independant of the ram table set option.

if you just want a clickable send button, you shouldn't use the toggled signal, you should use the clicked signal. toggled is usually for check boxes

[kur4o]

I figured that the hard way.

Here is the latest source code.
I got some issues to clear with your help and add some new features.
One of the main things is to send m4 message in two different lenght, based on some of switches in the controller window. Now it got really huge 24 bytes.

Other issue I got is, 3 different buttons control one bit. When one of the buttons is unclicked the bit is cleared even though the other two buttons are active. I need the bit cleared when all buttons are off.

The same issue with greying some of the controls because of conflict in m4 message. Some become active when they are not supposed to.

A nice feature to add is some mode 3 datastream in the controller window. A must for the closed loop controls. So you know the final value that is working the best.

Evening everyone

I've been out playing with kur4o's 4.90 version.
I'd just like to say excellent work sir, the individual fuel trims work well.

However i do have some issues.
Currently running OLSD as i'm thinking this is the cause of my problems in CL.

I think my problem occurs because the RHS O2 sensor is sat over 1 pipe of the Mac Mid length headers rather than in the collector, and it sees 1 strong pulse followed by some weaker/mixed ones.
I haven't checked/can't recall on the LHS where it's sat.

Watching the graph of the O2mv, the LHS is fairly flat, the RHS sits slightly lower with a higher rate of much leaner spikes.
RHS BLM's were always higher and i was running the individual fuel trim about 4-5% higher on all rhs cylinders at idle to even out the BLM's..

car is running idle at around 14.7 which is much lower that it has been.
Using the fuel trim adjustments tonight altered the overall AFR but didn't really show much change in the spikeyness of the RHS O2's.
I maxed each out in turn then had all 4 maxed on the rhs, it improved but AFR dropped to low 14's.

I'll have to double check which cylinder the O2 is sat in.

I know I've asked before but there doesn't seem any way to correlate which cylinder the data log is referring to so i can reference any changes.

Over the weekend i tried tracing a data log to work out which cylinders the log represented but again nothing that made much sense.
As stated previously, Gary Dougs list of the Cylinder ID differs from Kur4o's. The sequence is the same sbc sequence but shifted out.


Idle is 825rpm / 60 == 13.75 records per second ....... we are logging 10ish per second.
Target AFR 14.7

I was actually trying to work out how many logs behind the wideband was compared to the O2 data but was again inconclusive.


Thanks
Mitch

i've used the same headers and ran a different o2 delay time on the further sensor, that helped a bit, but ended up going open loop too

I have just tested the new maf table control feature and it worked great. Ultra fast reatime dial of maf table. Now I need to find a way to extract the table from RAM before it gets reset at ignition off.
Also tested the closed loop controls and can confirm they all work as they should. It is an updated version with some more stuff added. The first version got some bugs and might not worked as expected.

It is real hard to tune with 02 mounted on one of cylinders only. If there is place to mount the 02 between the collector and y-pipe, go for it.
The cylinder id also got some delay since it must go from e-side to t-side via spi communication and than the value gets into the aldl datastream.
You can try custom speed log. First open datalog, main -> uncheck stream button. Open raw window and type 03024301240125, set the delay to 1ms and check loop.
Fisrt byte on the repons will be cyl id, second and third left and right 02s. You can analyze gathered data and see if there is a missing cyl id in the log.

Another way to figure the idle trims is to disable cylinders one by one and watch how much the wideband afr and map jumps. You should try to even the jump on all cylinders by the same amount. The goal is to equalize all cylinders. Than the afr readings should be fairly constant with no jumps. Best approach is to tune most of the fuel related stuff in open loop.

I have an improved version of open loop idle patch. It sets the blm to 128 in blm 18 on low mph and goes to open loop in blm cell 16. It is tested and works great. If you got cl problems on idle only it helps alot.
