dual fuel disables ign map 3 and trans brake stays active
I had my car on the dyno this weekend on ethanol and noticed something wierd.
I enabled dual fuel based of flex so i can have a different accel enrichment table. When i did this, it disables my ignition map 3, even though alternate ignition maps is set to Off but still referenced it in the log (luckily). The fuel maps arent effected until you turn on alternate fuel maps.
Also, when using the trans brake function, with the input pin set to "same as launch", the trans brake is still active above the shut off MPH in the launch settings. This is incredibly dangerous.
Ill update the post with a MSQ and log in a bit, but i will not have a log capturing the transbrake issue.
In other news, the car did great. Made 775 on 24ish PSI with soft soft timing on a mustang dyno.
6.0LS
Twin turbo
Turbo 400 trans
MS3 Ultimate
Edited for more info

Re: dual fuel disables ign map 3 and trans brake stays activ
May I ask how you found out about the trans brake? I posted about this before and have been meaning to unhook my brake and put a test light on the output and see what happens. My brake and bump are steering wheel mounted

Re: dual fuel disables ign map 3 and trans brake stays activ
Because i accidentally hit the button driving down the road and it began to lock up. For whatever reason it wasnt instant and i felt the car begin the slow down and i let go. Im sure my transmission wasnt happy.

updated with tune and MSQ although the dual fuel and transbrake is turned off, but turning them on with the current settings inside would yield my results

That's the launch settings, they aren't linked.93supercoupe wrote:Also, when using the trans brake function, with the input pin set to "same as launch", the trans brake is still active above the shut off MPH in the launch settings.

Is this in the MSQ you posted? I don't seem to be seeing it.93supercoupe wrote:I enabled dual fuel based of flex so i can have a different accel enrichment table.

Re: dual fuel disables ign map 3 and trans brake stays activ
Yea, this MSQ. In the tune posted "dual fuel" is off because i needed to continue to tune the car, but simply turning it on will disable ign map 3 (even with out turning on alternate ignition)
Ill post a screen shot

Re: dual fuel disables ign map 3 and trans brake stays activ
Is this a glitch or this intended?
Also, should i make a new thread about the trans brake? That seems pretty obvious that it should shut off above a certian VSS

It is a greying error corrected for the next beta.93supercoupe wrote:Is this a glitch or this intended?
Nobody else has mentioned this before. Surely you'd have the same issue with a regular standalone transbrake ?Also, should i make a new thread about the trans brake? That seems pretty obvious that it should shut off above a certian VSS

Re: dual fuel disables ign map 3 and trans brake stays activ
Surely i would, but hardly a reason to not have a vss based shut off for a device that could stop you dead in your tracks at speed.jsmcortina wrote: Nobody else has mentioned this before. Surely you'd have the same issue with a regular standalone transbrake ?

And great news on the greying error fix!

There was this thread here where I meant to get some data, but have been dealing with a boost creep issue since the car got on the road I forgot about it

Re: dual fuel disables ign map 3 and trans brake stays activ
For the next beta, transbrake will only activate at very low speeds (< 1ms-1)

Re: dual fuel disables ign map 3 and trans brake stays activ
Fantastic.
Is it worth just having it use the Launch settings when "same as input" is selected for the input?
Or maybe just a user defined VSS?
