Fuel Pump Prime Time

[Martyn]

Anyone know if the time the fuel pump primes for is adjustable via a constant? Since fitting an aftermarket fuel pump my fuel pressure bleeds off shortly after priming so it often takes 2 attempts to start the car.

Thanks in advance,

Martyn

Which pump did you fit Martyn?

[Tomba]

maybe K_T_EKP_ON -> Minimale Einzeit der EKP

[Martyn]

I did see that one but the default value of 100ms threw me. Seems too short to be the 'prime time'.

[Tomba]

That was my thought as well, I can't find anything in the funktionsrahmen or a2l file that should represent it. Maybe measure the "ON time" with a oscilloscope or logic analyzer to know the time and search for a re presentable value.

I keep hearing about this funktionsrahmen, and would love to find/purchase a copy....

Me too, some have it but won´t share it/sell it. But you can buy it on a russian website for around 200 Bucks. I would buy it, but not for that price only because of personal interest.

Hotsd101 uploaded it here (post #7 second link). It is not the MSS60 funktionsrahmen documents but the MSS54. If anyone could share the real MSS60, it would be great. Thanks

^Is it confirmed the above is indeed the same as the MSS54 Funktionsrahmen? If not I have group buy going...

Someone very kind gave me the MSS54 Funktionsrahmen and I didn't see any differences with the hotsd101's documents, expected MSS54 is replaced by MSS60 at the top of each page.

The real MSS65/MSS60 Funktionsrahmen seems to be here :

(Sorry Martyn, we are off topic. Like Tomba, I can't find anything in the funktionsrahmen or a2l file to adjust this ON time)

K_EKP_START_ENDE it probably what you're looking for, the conversion should just be "x" so it's 10 seconds

I tried that, no different.

Do you mind sharing that, as I would like to double check...

I think the EKP_START_ENDE is defined incorrectly in the CSL definitions, I know it worked on the US SMG I was using at the beginning. I recall I found the correct location but I'm pretty sure that copy of my XDFs aren't around anymore. I've definitely gotten it to work before though.

In the CSL partial binary, EKP_START_ENDE is located at 0x4117
