I deleted DFCO to cure a backfire condition that happened on the let off. It worked just fine for a little while but one morning when I started the engine it ran real rough for a few seconds then...
Cam timing might be different that's about all I can think of
I don't know if mitchell's online manuals cover Benz or not but they are complete as far as wiring diag. They can be downloaded but it will cost $20.00 for the info.
I used the serial info wires...
Well I don't know why but this afternoon I went out to try to do another crank relearn, somehow it corrected itself. The DTC for crank relearn was gone and it runs just a little different. I will...
Have you ever had to relearn your crank sensor. I remember you had your 1.4 in a race car.
I am having one hell of a time trying to get mine to relearn. The first time I go thru the procedure it...
I have gone over the engine so many times I think I will just leave it alone and drive it as is. The reason I started this was that when cold it will not take any throttle at all. It has to warm up...
yeh that's the procedure I use. When it's preformed the first time it gets to the end and says relearn failed. Then for the next 8 times after rev up it says must be in park or neutral with engine...
A parking brake is not required in this app. Yes I do have the correct procedure for crank relearn. For this engine and trans HPT is more than enough to do this and when going thru the procedure it...
I installed the brake position sensor and tried to do the relearn 5 times it won't reset. Anyone got an idea why?
Thanks, but I will wait and see who can help with HPT. I have tried to find the info in the forum but so far all I have gotten is "no match" to what I have entered to try and bring it up. Maybe...
Can someone tell me the procedure for crankshaft relearn for the 1.4t. The engine is in an off road buggy so the normal procedure will not work. I would need a park brake pedal and the correct signal...
How much difference in tuning would there be at these levels= 12.9psi/3500ft. when seal level is 14.7psi?
The back fire on let off is back, I'm not sure it was gone at all. I have changed several things trying to fix but so far no change. This is the tune now anybody got an idea what I might try next?
...
I changed timing, fuel, throttle pressure and wastegate bov (not all at the same time), now when I pull hard and let off with short pause before hitting it again it lag's some before it pulls hard...
If that orange valve is not in there anymore you need to do the updated pcv now. Without that valve your loosing pressure in the intake into the crankcase and the vent tube that runs to the turbo...
I found my problem, the check valve at the turbo was stuck closed. I found another one and changed it out problem solved. I put my pcv at the original hole for the breather tube in the intake that...
If you haven't fixed it yet try this DFCO, extreme cutoff, you may have to reset it to a high setting. I found this out a while back and set mine to 6500 fixed it.
Simplyjesse; I hope you got it fixed that way. I found out with mine that the excess pressure from the turbo is getting into my crankcase. I'm not sure how yet, I did a compression test 148 to 155....
Simplyjesse; I disabled DFCO like you suggested and it worked great to eliminate the backfire on let off, Thanks. I checked out Goat Rope Garage concerning speed density and MAF cal.. I retarded my...
I will be going thru that again. I'll just keep at it till it breaks or runs better.
Thanks I will do that and give it a try in the AM. It's raining right now with lots of wind, I don't really want to get wet after all it is an off road buggy no windows.
Off subject a little have...
That sounds good, do I disable ECT, RPM, vehicle speed or just extreme cutoff. I'm not trying to sound stupid but I just don't know. I haven't touched injectors, MAF, or VVE yet and I am not sure...
I new I had a real problem but I thought someone might be able to spot it.
Will someone tell me if they see where and why this 1.4t is back firing on the let off. It may be there but I don't see it. I thought it might be the spark plugs but there isn't any miss fires under...
