CAN control has higher priority
I think it would be nice to add clutch pedal rpm increase in idle/target/parameters. For street cars if idle is low soon as clutch is pressed it would idle up and help start moving.
In theory the Above VSS RPM increase should solve this issue.
When you start moving the vss is higher than 0 and target increases.
Nah, i tried bad feeling, and that first torque is not there, also when clutch partially connected there is rpm bump what makes things worse.
Also i dont see a way to invert clutch position, i using oem ecu clutch sensor signal from e90.
I was going to suggest this idea a while back when tuning idle control
Very helpful moving car around garage and loading trailer. My VW Tiguan has the same when the clutch is depressed on idle get a bump of RPM and car can be moved easier with less throttle input.
ok guys. I will add it for next build.
Just got access to the V3 software and it looks to have some great changes.
However, when migrating my file from V2, I noticed it’s missing VE blending. Please bring a way of doing that back. I understand the theory behind ethanol correction, previously called ethanol fuel scale, but in my experience this is an unreliable way of doing multi-fuel with precision. Simply implementing a correction relies on PERFECT injector calibrations, which just doesn’t happen. Sometimes you get mystery injectors, the voltage is not consistent between injector and ECU, fuel pressure isn’t spot on or static, the list goes on. Using VE blend to account for these discrepancies has always worked great.
I’d also really love to see an option to set pre-throttle pressure as the Y axis for DBW characteristic. Using MAP can cause some nasty oscillations.
Thanks.
this is the new replacement for VE blending
hope this helps
you can use also clcustom correction table and set one of the axis to ethanol contnent.
Nobyou can for example to use VTEC and two separate VE tables + Flex fuel.
Custom correction tables will be very annoying to tune and implement being only 3D. VE blending is the 4th dimension needed to do this reliably and simply.
Nothing in tuning is ideal or perfect, and is often very far from it on customer cars. You sometimes have to tune for effect, and blending VE is a great way of doing that for multi fuel. Again, simply using a correction relies on PERFECT injector deadtimes. Here’s an example of a customer car, on which I spent a good deal of time on part throttle and cruise on both fuels. This is with off the shelf injectors using the manufacturer’s provided calibration. Sometimes we get customer cars with mystery injectors which make this even more extreme. This is the E85 VE difference over the E10 VE. I only went up to 140kpa on the comparison as that is all being run on E10.
I just don’t see how using a multiplier and correction tables could possibly be as easy and effective as tuning VE twice and blending.
Ok, I add VE blending for version 3.040 as an option.
Thank you!
Regarding pre-throttle pressure as y-axis for DBW characteristic, do you think that’s a possibility?
It is already added for version 3.039.
You can select between RPM, MAP and prethrottle boost sensor
Excellent! Thanks Jadzwin.
This is great news, we are running ID2600X injectors on flex fuel, and unfortunately due to the non-linear flow characteristics at low DC, getting idle correct between unleaded and E85 has been a nightmare. This is a very welcome addition!
so the car has a ve of 220?
That’s a part of the table it will never hit. It’s about 120 VE max on pump, and I don’t use the ethanol fuel scale because of nonlinearity of the sensors, so 164 max on E85.
There is no way an engine have 100 ve at idle. There is some thing wrong with the calibration
Would be nice to get some feedback.
Also there are any plans to update BT App? Canswitching over App would be nice
