Stumped need help!!!!

if they don't get the codes with the other chip it is because I run the ICP at 500 psi and some injectors don't idle properly there if they have odd wear issues. I've seen it several times.

Did you ever check the map sensor?

If your truck runs smooth forget about those CCT codes and focus on the actual problem.

Tncoalroller88 · Nov 17, 2012

so matt what ur saying is if the truck runs ok its prob because of the low icp u are running.. and dave what do u mean check the map sensor iv tried scanning everything with ae and all i get is the 1 3 and 7 balance fault code.. it just seems weird that they are all n the same head its like alsomt half the danng motor is out of balance i would think if it was the injectors it would be all of them or one of them or maybe two in seperate heads but not all three in one head the injectors are almost new

to the top!!!!!!!!!!!!!

If the engine runs smooth forget about the codes!

Anytime you change the injectors/ tuning from stock you cannot put much faith in the CCT tests, not that you can really trust them on a bone stock engine anyways.

Monitor the MAP sensor while driving, it should follow the EBP closely... dont forget to subtract 14.7 from the EBP.

well i guess ill see what i think about it monday idk tho tunes just do not feel strong to me

907DAVE · Nov 17, 2012

A bad map sensor or leaking reference line will make the truck run exactly like you describe.

Listen to what everyone here is telling you, and do some ACTUAL testing before jumping to conclusions.

Good Luck.

Agree with dave. You seen very fast to jump yo conclusions about the tuning. While I know its possible for tuning to be an issue, its also pretty likely you have a minor problem causing the strange throttle response. Also, what matt said about the difference between jodys and others tuning is true. I bet you're making cleaner and better power with matts but jodys have a better seat of the pants dyno power because of added timing and/or added icp.

I'm not jumping to any conclusions about anything just trying to get some answers about what's going on what real testing can I do I've ran the ae time and time again I get the exact same codes each time. And the truck feels like a slug. There is no seat of the pants feel to me at all untill u bury the throttle. With my old tunes id go up a pretty good grade withoug downshifting now I have to drop a gear or put it to the floor that is not my preference period I wanna feel the power from the top of the pedal to the floor not just to the floor. I've been driving this truck since it had 50 thousand miles on it and if always done my own work on it. So I'm pretty sure I know when something is wrong. If u have one asset of tunes and truck runs good then u switch n its a turd its prob because of the change

You are probably right, however you should have all your bases covered first.

Just so you know, there is more to diag than pulling codes and running self tests. Get on that AE an bust out some datalogs of things like MAP vs EBP, or ICP vs PW or ICP vs IPR%...etc.

We cannot help you without some actual data. Everyone can speculate what your problem may be, but its up to YOU to find the cause.

Not trying to be a dick, but more people might take the time to read your posts if you take the time to make them legible.

Tncoalroller88 · Nov 17, 2012

Yes you are right about making things legible. Most of the posts were made from my phone which makes it quite the pita to get punctuation n such exactly right. But coming down to it i just cannot see why after i change the tuning its doing this, it makes no sense to me that i get codes for cylinder balance. I have not checked for codes since i put the injectors in so they mayhave been there all along but fact of the matter is the truck feels like a slow turn with theese gearhead tunes compared to my dp-tuner i dont know if its that it has little throttle responce or the fact that i get power only at full throttle, hell that may be the way they are programed to be, but i just really dont care much for the way it is it acts totally gutless. Also the stealth tune makes it just bellow whitish blue stinking smoke, its driving me crazy....

sunday morning bump!!!

I'll gladly refund your money. I use the map sensor heavily where some tuners do not. I run stock icp at idle which some injectors cannot handle. I can make adjustments for the lazy injectors to fix the contribution errors, but if the map sensor isn't working properly it wont fuel right. If you are happy with what you had before just send my chip back unless you want to get to the bottom of the issues.

i would love to get to the bottom of things, and really hate to have to have my money refunded because i have really heard nothing but good things from people about the tuning.. i would really just like to have it fixed and i dont get how my truck could have a bad map sensor when it ran good with someone elses tunes. I will tho check my map sensor with Ae tomorow if u can let me in on exactly how i go about doing that? If its ok i would really just like the chip to have a somewhat more agressive pedal, at least where its not all or nothing. and have the stealth tune completely removed cause it just makes the truck fog with white smoke. My only dilema with all that is without a chip im stuck with my truck down for how ever long it takes to have it shipped back and forth and im out the money for shipping charges. I really hate to seem rude and like an ass but as i said something just doesnt seem right seems like it needs more throttle with it being a 6 speed manual than, if it were an automatic itd prob be just fine ..

Really?

What additional info do you have to help us? None of us can magically cure your problems without YOU making an effort.

Good luck.

YA really Dave really. YOu REALLY had to stick ur nose back in here where it dont belong again with some more useless comments. Thanks that helped alot. One more spaced uv wasted along with my time.!!!!

Gearhead · Nov 18, 2012

Check your map pressure sensor key on engine off. Then see if it agrees with your boost gauge minus 14.7 psi at say 5 psi of boost crusing. A map sensor not showing boost will never get fuel with my tuning.

907DAVE · Nov 18, 2012

Okay, dude.

Again, good luck!

Tncoalroller88 · Nov 18, 2012

oh so heres what i have so far idling
Map pressure shows 14.0
icp is 651-655
icp duty cycle is 13.28
exhaust back pressure is 0.89-0.92 volts
map hz is 0.0
exhaust back pressure psi is 14.21-14.61

the codes still show up as cylinders 1 3 and 7 have a balance fault. im gonna go now and do as matt has said in the post above n make sure the map is reading what it should.. maybe this helps idk
