6.ol 9r10 hiccups

[bdog1]

Hey Guys,

Had some recent work done on an '03 crew cab. Tech updated it to VXAP2N2.
Had to load the 9r10 to recognize. The 100hp makes it feel like it's missing. Sometimes when it fires up a puff of white comes out and idles erraticly. If you give it throttle it just "loads up" and no revs.

60 hp feels alright but not as much power as previous tune.

Any insight....is it an injector problem?

Cheers,
B

white smoke screams injector problem all over it from what i've seen. Getting any trouble codes?

Just a couple to do with glow plug no. 7 and the p1000 . I'll check again tonight. I only ran the 100hp for a short trip around town.
Been running the tow tune for last few days with a 9000lb boat behind it. Runs fine but starts up with a funny idle is the best i can describe it. At this point i think i better go back to stock.

Could be the egr cooler also.

Now that i think about it, the puff only came because i started it and it idled erratically so i immediately shut it off. Upon restart it puffed white, in my opinion because it was loaded with diesel.

Is anyone else having issues with this cal id and the new revision? I went back to stock but it's so damn boring to drive.

I am having the exact same issues, same calid ,same revision . truck ran great before, did not have a programmer before the 9r10 update so I can only compare to stock.

white smoke to me would indicate coolant, black smoke would indicate rich fuel mixture. I could be wrong though.

Does the 60hp do similar things at start up etc..?

[SCGt94]

I believe I have a fix for this, providing i get some more feedback. I need some more testers. I had a guy with similar issues send me and email and he said its working great now so I believe i got it down. Hit me up with an email and an ori and i will take care of you guys, then ill release a new crom with the fix.

Just the 100 hp setting causes the rough start/idle. Thanks Don!

Hold the phone on that fix, Don ! The truck started up fine two times, and then went to acting crazy again. I want to evaluate it a little longer to eliminate everythiing else. I want to try some more "true cold starts" because Im not sure the glow plug circuit is even working and Iwant to make sure it's not hardware related on my end. Thanks !!!!

[SCGt94]

No problem, i did however send this fix to a customer with very similar issues and it took care of it. Let me know guys

I'm way late reading this post. I also have the white puff come out and a wierd start up on the 100 HP setting only. If I run the tow, 60, or stock, no white smoke at all, ever. Go back to 100 HP and puff, white smoke. What was your fix for this? I'd like to get that tune. I have the '03 VXAP2, no error codes at all. Thanks.

k...send me a copy of your ori, the fix will be in the next revision but that might be awhile. I can write you a fix for the timing being..
