Beta testing has been quiet over the holiday. I think everyone is on vacation. Things should pickup again soon.

 

Oh wait, I completely missed that okay, haha...now how do u do that?

 

 

But those are the open loop tables....how do you make the car run off of open loop instead of closed loop at cruise....

 

The open loop tables tell it at what load and RPM to go into open loop from closed loop.

From the factory it is set to go into open loop at 100 load @ 4000rpm, 125 load at 3500 rpm and 140 load at 2500 rpm.

If you set it all to 0 it will be in open loop all the time, etc etc.

There is also a open loop throttle volt table as well.

 

Oh, interesting....

 

Ecuflash products in this thread only, please.

 

So Bryan what tables are these? What do they look like and how are they scaled and tuned to run open loop cruise?

 

Bryan, thanks for sharing your extensive knowledge! Does using open loop cruise require extensive logging and tuning to get it just right? I'd personally be a little scared to do this unless I had a permanent wideband o2 installed in order to monitor afr during cruise conditions. Seems like there would be a bit of trial/error to get this just right.

 

Well FYI you shouldn't be tuning your self without a wideband anyways, so you should get one if you want to self tune.

 

Yeah definitely need a wideband to tune, but I don't think you definitely need one permanently installed. Just wanted to throw that question out there since some people will have an LC-1 or ZT-2 but no permananent gauge used to monitor afr at all times. It just seems like it might be a bit tricky to get open loop cruising fueling right unless you're an expert like Bryan. So my question is, how hard would it be to do?

 

Well I'm gonna have a permanent install. Why not? Gonna have AEM Oil Pressure, Boost and UEGO WB. The best tuning and monitoring tools. Why not buy a UEGO and install it permanently into your DP? Be safe and if you ever want to retune you're set.

 

HAPPY NEW YEAR GUYS !!

MRFred has found the perephery bits !!

That means your O2 CEL for testpipes is a thing of history !! .. unti I figure out what the bits are 1st that is ..

 

Can't wait.

I must be lucky with my test pipe. I've been running one for almost a year and have never gotten a CEL.

 

yeah I have only gotten the secondary o2 CEL in conjunction with the 1235 overboost CEL. Funny thing is that I'm running off the factory boost control with just standard bolt ons. From what I hear though, it's easy to get these codes when you're un-tuned with bolt ons, unless I'm completely off base...??
