Wyoming B.S. Thread

Yeah I did. Way too much for how fucked up the cab is.

 

Epic last night as always…this concludes my once every two year post in the WY Tacoma/Tool thread

 

Do our trucks know what gear we are in and use a different ecu map based on that?

 

Nope, auto trucks know but there are no mapping differences it's just so they can retard timing during a shift. You're just hitting different cells in the same map because of load differences

 

yeah not that "smart" of ecus.

 

Map switching is a pretty fancy trick for an ECU family made in the 90s haha. I think the only different map it posses is the cold start enrichment map

 

Yeah figured, it just behaves a lot different in the upper gears. I hit a wall in 4th at 3k yesterday and couldn't get passed it. AFar of 10 and timing dive bombing to 5*. Third gear I can push through the trouble spot but 4th just, couldnt. It's making great power in these temps at least.

 

Lot of load at a spot of inadequate fuel adjustment sounds like, dick with your 7th

 

I had that issue in Frank if you recall. If fact most the time I basically slowed down. My solution was removing the 7th injector. ran better but of course pinged like hell.

10 is pretty damn rich though. So you might be over fueling it. Timing is probably getting wonky too

 

I don't have the tools to adjust the map otherwise I would.

At that afr I'm assuming too much fuel?

Yeah I luckily don't ping, which I prefer. Timing is the issue too, if it can keep above 15* of timing it pulls hard.

 

I'd dial it up to 11.3 or so, shouldn't ping at that and the timing should want to stay up. Can preemptively dial your timing down a notch with the 7th. I have the software for your 7th on a virtual machine that you can run on any computer.

 

should be able to use your new laptop to get into it. Just need a serial to usb adaptor.

 

You lost me at virtual machine.

 

I'm not plopping my $$$$ desktop into the passenger seat of my truck thank you very much.

 

I can send you a tuning laptop.. we have one with all the tuning platforms we keep at the shop. But really if you have any laptop at home I can walk you through loading the virtual machine and you can keep that

 

oh ha i thought you'd said it was a laptop would be funny to see that though haha

 

I'll have to see what cables I need to hook up. I may have a computer to use.

Well, I do have our old PC I could toss in with a monitor for a day of tuning......hmmmm

 

The stupid 7th needs a USB to Serial FTDI adapter if I remember correctly...

$13 SABRENT USB 2.0 to Serial (9-Pin) DB-9 RS-232 Adapter Cable 6ft Cable [FTDI Chipset] (CB-FTDI)

yeah. Mid 90s tech after all..

 

I am hoping to avoid all of these types of issues.
