Hey man I appreciate you, but I think next time i will be using Holley.
Ok I'll make it easier, what does the shift filter do?
Yeah thanks for responding, I'm asking about the special functions, the filters. What I need is to delay the tps and map to match up to the o2 on the scanner/ graph. I've been screwing with...
This should be a very easy question to answer for one of you pros. How do I filter in order to line up the tps map and 02? Come on man!
Hey guys I've been chasing down what I thought was transients but turns out it's the delay between the tps map and o2. How do I filter in order to line these up on the charts/ graph?:confused:
Well I thought I was at the final steps on this tune. Just trying to find tune. Pe tps is power enrichment throttle position sensor that's how it log pedal position. I was in the garage logging...
sure post your log and tune. what ive been doing is using ITT to adjust fueling during cold/hot start, but that may not be the RIGHT WAY. but be aware that 1st crank after adjusting ITT itll run...
it might help if I left a log:doh:
this is an example of what i'm trying to perfect. while idling I can push the skinny pedal and I get a lean spike followed by rich spot. the severity of the spikes get less as IVT rises, so I should...
Notsure, to be honest I just installed it and entered the FIC injector data and ran it. I haven't noticed any fueling issues, but i'm not a pro. at idle I do see a little fluctuation in fuel pressure...
thanks for proofing my tune. i live in the middle of nowhere and noone else around here that i know of is into this stuff. the closest pro tuner is about an hour away and he won't help. in fact he...
4.8 single turbo, 209/217 cam : Hey guys take a look when u get a chance. I've attached a log of crank and idle. The truck fires right up but is a little lean right after startup. then later in the...
Hey guys i appreciate the help.yeah GTS i realized what you were talking about when i looked closer. Now i need to do something with fuel. it cranks and runs @ 50ECT, but its rich as hell. whats the...
I added some timing like you suggested, and it did help, but it turns out startup fuel and the IVT tables were way rich. I took alot out of startup fuel and adjusted the IVT until ECTs got too high....
You mentioned the ECT adder table. Do you mean the table under min airflow? Add air in the hard to start temps?
here's another log and tune where i've made changes trying to fix
Hey guys, i'm having a problem with cold start on a turbo 4.8 running speed density. It starts then dies and at the end it shoots 50ms worth of fuel. Then when i try to start again, which may take...
Are you using a wideband? Tune the maf, first. It's easier. Be easy because the knock may be real. When you log see where the knock is and look at at the afr if its lean add some fuel.
It's been a while and this may not help but I used a card style with integrated iat and I had to swap the two signal wires then I found a tune on the repository that used the same maf and copy and...
Good question IDK, I've always used high octane fuel 95/93 octane and tune in the high octane spark and then subtract 4-5 degrees in the low octane spark just in case so the motor has somewhere to go...
Maybe timing related, check all temp related stuff. Mine was doing the same, very little input on go fast pedal and it would straighten up. That's at cold start idle. Lakegoat suggested to add to...
Oh hey 5f, I did the 3 bar just in case I want to do more later. And yeah the kpa isn't exact as of right now it should be 102.3 but close enough right. As far as the injectors I believe they're...
Thanks. I did adjust cranking fuel and ivt gains( took some fuel out) today and it seemed to help.
I don't see why not, but you should get your laptop up and running if you want to tune. not trying to be smart but gotta have a laptop IMO
