Title: Issue with RPM limit when not driving/rolling Post by: OddWorld on December 18, 2023, 03:10:54 AM Hi,
I'm building an a-tractor (30km/h) for my daughter out of an Audi A4 2.0TFSI MED9.1.5 (2005) and I have managed to get most parts right but there is one small thing that bothers me and I wonder if anyone knows if it's possible to fix/adjust. I have set the RPM limiters on all gears according to the real RPM at 30km/h, and also set VMAXNB to 30. If I remove ESP-fuses the car will be limited to the RPM set at NMAXGA "0" (which I have set to 1000RPM because thats the highest I can have because of only disabled gears 5 and 6 physically on gearbox) This works good as a safe solution if ABS fails. But this 1000RPM limit is also active when I start the car, and try to take off, so it gets real hard to drive until the engine is warm, since it does not reply to pedal at all, since its already at 1000RPM before getting warm. As soon as the car is "rolling" this 1000 RPM limit goes off and I can rev whats set in NMAXGA on gears 1-4 (for example 3700 for gear 1 etc) I'm due for inspection tomorrow and hope to have this fixed before that :) Hope you understand my concerns.

Thanks for your reply, I have not found any translated module for NMAXHD, but will see if I get any wiser running the FR in google translate. I assume it's something really simple that I just have missed, hopefully I get it fixed soon. Title: Re: Issue with RPM limit when not driving/rolling Post by: OddWorld on December 18, 2023, 06:40:26 AM I'm trying to use NMAXOGGA but how do I set b_nmaxog = 1 ? I don't seem to have that value in my file.

Title: Re: Issue with RPM limit when not driving/rolling Post by: OddWorld on December 18, 2023, 07:57:59 AM Looks good, thanks. I wonder if it's possible to set VNMX to 0? or how to make it active when car is stopped?
And: If VMAXESP is active (having problem with ABS-sensor rear right) will it still be possible to achieve NMAXOGGA with VMAXESP active?

Title: Re: Issue with RPM limit when not driving/rolling Post by: OddWorld on December 19, 2023, 03:33:43 AM I tested with just a few changes yesterday, it's still the same.
Not sure if it has to do with car being in VMAXESP map because of the failure on rear right esp-sensor. So I just leave it like this until I managed to replace it. I think it'll pass MOT anyways.

I guess there is no solution to my problem since VNMX can be set to 1.25km/h as lowest? (meaning I can't make NMAXOGGA while standing still?) Is this assumption correct? BR OddWorld |
