Re: Flex fuel sensor

Are you sure it's wired correctly ?

Exactly what sensor is it ?

You also mention you used chassis ground....whilst it shouldn't really matter, isn't it normal to use sensor ground ?

Re: Flex fuel sensor

Strange...seems to work fine on my S8 like that.

How are you determining it is not working ? Have you tried putting ethanol through it and seeing if the composition reading changes ?

Re: Flex fuel sensor

How do you have the input configured for fuel composition ?

Re: Automatic Transmission Control settings

1.680 for the S7, S8 and S12 will be released soon and this has lots of updates to the Automatics Trans control to support the 8HP Boxes. Lots of new Custom map options for Shift RPM points, lockup duties, Line pressure etc Would that be control via the onboard TCM via CAN or whatever or does it re...

Re: WOT from low RPM vs high RPM

10% per 1 bar may not be enough, and your table assumes a 4 bar base pressure ? in that 4 bar is x 1.0 ... yet your logs seem to show your base is 4.7 bar or so ? IMO for ease of use, set the x1.0 multiplier to whatever your base relFP is, and then go up and down either side of this to maintain cons...

Re: WOT from low RPM vs high RPM

I need to fix oil and fuel sloshing. Indeed you do. Although even the video shows no data relating to fuel or oil pressure. And you are maybe misunderstanding the importance of that relFP fuel multiplier. It IS the fastest response to a falling fuel pressure to try and retain some normality to fuel...

Re: Full H-bridge

I'd also probably wire it with an inline fuse, you could always remove it once you're happy if you didn't want to keep it there. It's a good point...and for any "power" ecu outputs too... Do they even have any overcurrent protection built in ? For the internals themselves, or indeed the external wi...

Re: WOT from low RPM vs high RPM

Or if you had relFP compensations....fueling may have stayed close to "correct" anyway, despite the problem.

Use that, and the relFP safety trip.

Re: WOT from low RPM vs high RPM

Clearly at lower loads, the system is capable of making pressure....otherwise it wouldn't be dropping under boost. You could bench test at no load by applying pressure to the FPR, although as there is no loss in the system ( ie the engine ) it's a little bit of a false test, but it would at least ve...

Re: WOT from low RPM vs high RPM

I doubt it. Seems more a pump/filter/wiring, ie. fuel flow problem problem.

And get that safety on relfp added !
