This is the 2nd unit.... still doing the same thing.

 

did you verify that timing is being pulled with the br-3 when you use the ftc to retard it?

 

that we did do. yes the timing was being pulled. but then its like the ftc decides what it wants to do for the fuel portion of it... which is causing it to run lean.

 

Can you post a screen shot of your map?

 

i can but itll have to be later tonight sometime.

 

I was out jogging and was thinking about this. Think you might have a bad or poorly connected injector?

 

The detonation occurs where? Above 3k?

 

Catching up and filling in around the edges...


A normal TPS range as seen through OBD should be 10% on the low end to 75% on the high end.


Remember that Open Loop will come on based on a number of things... throttle position, air flow, "computed engine load", and I think something else.


Like Gregg (Greedy), I've been there too. My truck is currently coming into it's 2nd month of being down, for the 2nd time. I was hosed from 8/2006-11/2006, then completely down from 11/2006-1/2007. I had one good month up, then hosed for a month, and now I'm completely down again.

p-r-i-u-s.

 

Right. This was just a quick test for me to see open loop on the laptop. I'll do more thorough testing when I tune.

Why do you three guys seem to be having so many problems? Midiwall I know you had some failure a while back, so that could account for some. I don't see anyone else on any other forum being down like this. Are you guys just major tweakers or ?

 

Coolant temp maybe, I seem to go into open loop very easy when the coolant temps are higher than about 215 deg F.

 

If you're thinking about my valve burn, that was "fixed" with a many-thousand-dollar very-complete engine rebuild from the ground up - you'd think I'd be running really well right now.

I'd say that Gregg and I are pretty top-end tweakers, but there are other folks beyond where we are right now. Some have trouble, some sit on CT and say "I dunno why you're having trouble, I've got 25lbs of boost and running great!"

Gregg's issues for a long time were FTC1E based, he's a lot better these days after getting rid of it. Before that, remember that his turbo install is 100% custom. His truck was out for 6 months while tubing was bent, intercooler was being custom fit, etc.

Me right now... hard to say. I have another thread running with the present symptoms. I tend to refuse to believe that the issues are internal, but it's kinda' pointing that way. Personally, I haven't had the energy to dig into this thing for a week or more, I'm pretty fed up.

 

Its a good thought man, ill have to check that out. for i dont have the solder type connections, they are the clip on converters. so no need for cutting the wires.

But would you think there would be miss fires and such with a poorly connected injector? Should also through a code too.

 

I'm not sure what codes it would throw, if any, since the injectors are not stock. I believe a misfire could occur but not sure how the new injectors would effect that.

This is all just theory though, but I'd definitely check it out.

 

It happens in any rpm, high or low. at mainly 2-4psi.

 

And you have the 170 thermostat installed with the jiggle valve at 6 O'clock right?

 

I do not have the thermostat. The stock one is still in there. But that will not be causing all the issues im having. Already discussed this with Blink.

 

the thermostat i'm pretty sure helps alot with pinging. ie less heat?

 

You're right it won't cause all these issues, however it helps the pinging immensely. I just had a buddy drop one in his Taco and it virtually eliminated any ping.

He also did some Water Wetter in the radiator mix.

 

(in my case)The Pinging was due to the timing. We corrected that with adjusting the timing. But now its leaning out again. Which in that case it pings due to being lean. 16:1 AFR is not healthy for 2 psi boost @ 1500 - 2500 rpm. Let alone it hits 16 afr in open loop with it @ WOT.

Im 100% stumped on what the hell is going on. Fix one side of it the other side wiggs out.

All my connections are secured and soldered. If i ever get time i will have to remove the S/C and take a glance at the injector connections. But i triple checked those on installation and pre-installation of the s/c when i got it back.

Im just one of those unlucky people where nothing can ever go right (EVER).

Interesting --- I assumed that the lower tstat richened the fuel mix, but that makes sense too... 10 degrees can really change things on the combustion front. TRD ships a 160 with the 7th --- is that how they take care of the ping? Not necessarily with fuel?
