Then you change a setting in the software to enable it.
Log it during your logging stuff.
Then we figured it out... silly config problem + less-than-perfect Halwin software (no data verification):E6X Halwin 1.26 Supercharged Lexus IS300
Zeitronix Wideband, Bosch 0-5v o2 sensor
Wired up everything for closed loop operation today, after much ado finally got the Halwin software to display the o2 output from the wideband correctly.
Enabled closed loop, above 700 rpm, under 25% throttle, above 175* F. 0-5v, bosch wideband sensor
Target voltage was 2700... the reading in the haltech when my external wideband display said 14:7...
Problem is, the X doesn't seem to care about the tagret voltage... all it does is dump the max fuel all the time (according to the halwin text data display and my external wideband display.)
If the voltage is under 2700... all I see is dumping 10% fuel. If it's above 2700... it still dumps 10% fuel. If it's exactly 2700... yah... +10% fuel.
No matter what I do I can't get it to do anything other than +10% (or 5% if I change the max to that)... changed through all sensor types, rebooting car in between. Set target voltage ridiculously low, ridiculously high, reset ECU, reload map, etc.
Only time I see anything other than +10% is when I go above 25% throttle... then it instantly drops down to 0% so I know that part is working.
Any ideas? Do I have to sacrifice some sort of chicken and let the car sit for 3 days after enabling closed loop for it to work correctly?
Well, this was one of though "doh! who woulda thought it worked that way" things.
Max Richening factor: 10
Max lean factor: 10
Based on it's logic, the haltech said... "Whats the maximum amount of fuel I can PULL when I want to go leaner", saw 10 as in POSITIVE 10%... ADDING 10% fuel, and said, "Well, I can't take away any more than adding 10%". So thats what it did.
Switched lean factor to -10, with a negative sign, and it worked like a charm. When it wanted to pull fuel, it said "How much fuel can I pull" saw -10% and was able to REMOVE 10% (Obviously the ECU interprets it as ADDING NEGATIVE FUEL)
Lack of error checking/validation in the halwin software and silly forgettign a single keystroke on my part. Whew
Not really auto-tune... only closed loop fuel management, just like the IS300 ECU hs in the first place.IceCold4x4 said:^ So how's it working with the auto tune?
I am psyched I can finally read this thing in standard measurements.dasgalloway said:Not really auto-tune... only closed loop fuel management, just like the IS300 ECU hs in the first place.
Still working on the tune a bit. Seems to be working fine, just have to dial some things in. Sometimes at idle it hunts back and forth and can't settle on the right AF... might just hand tune it for idle and only used CL for daily driving
