MY 3.2 swap mk4 is running like a bag of crap

kts 650?

cant beat that bosch gear - top stuff.

 

will check part number on FPR......i think I may have used the 2.8 one you know....

 

650's are a bit bulky and limited, got a 550 and use the laptop with all the other software on and info + use a Pico instead of the KTS scope

Had a few gripe with the KTS software, I’m not on Bosch technical’s Christmas car list anymore but they are very good compared to the competition

 

the bfh engine(r32) got part no of .... 078 133 534c

the bde is 037 133 035c

i DEFINITELY used the 2.8 ecu. I had to buy a brand new fuel rail as the original one got mashed in the crash.

bugger, my audi lump doesn't have one, it's a different setup. i bet they are a bloody fortune.

 

Should say the pressure on ETKA, if 3.5 or 4 bar. If it’s got an incorrect pressure reg you can fit an aftermarket unit after the reg but not sure about the vac pressure increase

 

If we look at the fuel trim and crimp the return line a little (could do with checking the pressure at the same time) the fuel trim should come back into line, that’s if it is a pressure problem. First thought is an air leak tho

 

I'm sure it's a 4.0. will check part number tomorrow.

makes sense now. that would tie in with why the mpg figures on the mfa are really low, yet I'm still getting similar amount for miles per tank

if the pressure is low and it's having to increase the injector pulse to get the fuelling up to scrath then that will throw out the mfa as I'm sure it works out the fuel usage by going of the injector open time (i.e. it knows what the pressure is (should be) and know how much fuel the injectors use).

 

i got a fuel pressure reg for mine from ECP. it was a pierburg item, so not a completely no brand copy etc

 

i think these are bosch items.

 

well, it did have the correct 4.0bar FPR after all.

back to square one.

Really worried about it now :-(

 

Did you check the position of the lambdas as per our prev conversation??

 

no. the way the wiring is routed around the heat sheilds makes it impossible to get them in the wrong cat.

 

lad in work said that about the cam position sensors, until they got swapped around and it ran well

none of those faults though, miss firing on 1, 4, & 6 have you tried to clearing faults and swapping coils around see if misfires migrate
misfire detection should be in measuring block 15 & 16 - block 4 needs to read active

idle control, with multi mis fires could be linked, only other thing would be vacuum pipe off or air leak, and of course the valve to the exhaust valve flap not wired in yet -the vacuum line going to that blocked off??

if you have stuff to take oscilloscope of output power of coils (touching lead on top of coil) common for the secondary discharge spike to be missing, but still produce enough to burn fuel

 

It's looking more like a vacccum leak really. that would explain the secondary air pump not kicking in, the solenoid not opening, possibly, the lean mixture, and the lumpy running.

Need to pull the front of the car off to have a proper look at it. haven't got time to do that for another 2 weeks :-(..........

 

Daz does your fancy gizmo diagnose FIAT problems too? [apart from it being italian etc] might have to wash it after like

 

Model etc and I can check in the directory + year as OEDB gives loads of data, if its for you Ill only charge you 67553778.00 per hr half price then


Paul, if you get chance you can always have a run down as i didn't get to Harogate

 

i was going to go to ultimate dubs in the country, might come though in the 4 mo if you're about sunday late aft?

 

i'm out on sunday but at work all day on sat if thats any good??

 

Laura's 30th birthday...... (all day....) so i guess I can say there is zero chance of me doing anything remotely to do with cars on that day (except drive her about)

 

Shes got to make you have at least one day off from the cars
