not sure how much diffrence there is a lot of the plugs are the same i think the plugs for the injectors may be diffrent but not had a look yet are you thinking it will easer to rewire than get a mk4 r32 loom the post 2001 4motion loom is not that diffrent from the r32 loom it's only the early 4motion's like mine that are[:^(] its just a shame my mk5 loom is so cut up
I have no idea. I'm just collecting the bits for Andyout but I'm trying to understand as much of it as possible. A guy on edition 38 fitted a mk4 fuel rail and uses the mk5 injectors in his mk3. Another guy doing a corrado is using the mk5 loom and ecu with the mk5 injectors and mk4 fuel rail. My engines comming with the mk5 loom and ecu but I have wanted adds for the mk4 stuff. Do you hve a close up of your mk5 fuel rail showing how you added the FPR and return?
OK, i'm talking to a guy about a loom but he says he doesn't have the left hand loom. He thinks it has the lambdas on it and maybe more. Can anyone offer me some advice about the engine loom/left hand loom etc...?
yes it has the lambdas /air meter/secondary air pump /charcoal fillter and some i cant make out from ETKA i take it when you say left you mean drivers side can print a picture of the page if you like
This is what he has but the bits in red are cut/missing. He is being a great help and explainig to me whats there and whats not, also the part numbers for the missing plugs etc... Is that what i'll need to get the engine running in my mk2 or will I need the left loom as well?
you are not going get it runing with just this you are going to need some of the other loom as well but it is a very good start how much of the mk5 loom do you have or do you not know yet
I'm not sure yet, still waiting on the engine. I'm still unsure of why I cant use the mk5 loom and ecu with the mk4 fuel rail.
it would be nice know more about mk5 fuel injectors ie flow rate and pressure they work at i have looked but not found anything yet
A guy on E38 runs a mk3 golf with mk5 engine (on emerald) and uses mk5 injectors with a mk4 fuel rail. Surely injector plugs could be changed easy enough, this pic is vento mikes:
Emerald is calibratable top suit a shift in injection rate. Motronic is too but will hit either lambda regulation clip or fuel adaptives. This will lead to EOBD fault! My 2c if you are going to use OE controls do not mix and match components from one controller ME9 to ME7 unless you know how to remap the ECU yourself and you know the spec of the items you are mixing and matching.
Yes, your right Toyotec, I should stick to collecting the bits rather than thinking too much about it. Although people do use the mk5 injectors so i'll leave them off the list. I now need mk4 engine wiring loom (left side), fuel rail and DBW pedal. I will get a friend to attempt to modify the standard downpipe to fit.
if you can get the part numbers from both mk4 and mk5 injector i may be able to look them up for you. i need the bosch/manufacturer part number ideally but i may be able to look up the vag number as well
I've bought the loom and ECU now, i'm sure Andyout will be able to piece in the missing plugs if I get hold of them. I'll have the mk5 loom that I could cut but i'm hoping to sell that one to pay for this one. If anyone see's a left side loom or complete loom (Mk4) could you let me know. The guy I bought it off thinks the V6 4motion left side loom is the same, can anyone confirm?
the ones i have out of the mk5 r32 engine are bosch = 0 280 158 121 vw pn = 022 906 031L the mk4 r32 is bosch =0280 157 012 vw=022 906 031J (193 g/min at 3 bar)
One of the calculations performed in both types of ECU, the ME9 return-less and the ME7 with conventional FPR, is to convert fuel quantity into injection time. To perform this calcualtion the "Qstat" of the injector must be taken into account. The Qstat, used in calculation is determined when tested with heptan at nominal fuel pressure and is measured in g/min. This differs from the publised flow numbers, measured in ml or cc/min. I will list the data for both below. Note the Qstat is different between ME9.X and ME7.X.X R32 injectors. VAG # Bosch # Qstat@3bar g/min Flow rate ml/min Resistance O Type Length mm MK5 R32 022906031L 280158121 187 267 12 EV14 78 MK4 R32 022906031J 280157012 193 276 12 EV12 81 I would suggest sticking to control hardware that the engiine came with.
I was under the impression that later engines using fsi injection uses a 5v feed for the injectors and this leads to problems with error codes and component communication, error codes and the like I could easily be wrong on this but thought it may help, Useful thread this keep up the good work
I think FSI 3.2's are only in the A6 and Tourag. Is the difference in flow rate big enough to make a difference in the running of the car?
The injectors spoken about above are for port injected engines. Direct injected engines (TSI, FSI, T-FSI) have different controls and components.
Ah ok was under the impression this was a potential plan using the mk5 fuel system My bad ignorable stupidity
