There is a couple of groups on Facebook dedicated to T4 engine swaps. Lots of helpful people on there. You can't really ditch any sensors from an E-VP37 install. You could run without a MAF but the tuning time and cost would far outweigh the difficulty of installing a MAF You can ditch anti...

I recently discovered a website called tunerfx.net after what appeared to be a spam bot messaged me on ECU connections. I was pretty desperate to get a tune and I could find no tuner except darkside who would touch it and they were very expensive and a long way from me. Anyway I was pretty...

What IQ have you scaled your Pump voltage to if you don't mind me asking?

I would take people claims with the 10mm pump with a pinch of salt. I would suggest that you get a 11mm pump. I have tried with several cloned MPPS cables various versions and never got them to work. So if you can get one to work your already head of the game There is a great YouTube...

You would need Winols to alter the maps and something like KESS V2 (EU version)to flash the maps. Presumably your not going to be purchasing these from legit sources. So you will need a Laptop with Windows 7 on it. EBAY is a good place to find these things. Tuning is basically the hardest...

Have you removed the injectors in recent history. First time I removed a set I had to buy the biggest slide hammer you ever seen to pull it out. After that it's been easy. But if they have never been out they can be hard to remove

What did you weld it with? I had issues historically using a MiG with mild steel. I have seen there are some rods that allegedly work with cast..

The piping is all different between valves I believe. So make sure the diagram you use is for a wastegate setup

AFN will be a vacuum N75 aHU will be a boost N75

Sounds like you probably still have a boost leak. N18 is the valve for the EGR. I presume you meant N75?. N75's are not all created equal. Some are designed for boost and some for vacuum. Maybe you fitted a vacuum one erroneously. You need to use VCDS to really diagnose it. Could be loads...

There should be a one way check valve on the fuel pump. My understanding is that it is built into the return fitting although I have never checked. Depending on where the fuel pump came from and where the fittings came from, it may not have it or may be faulty. I believe land Rovers didt have...

How is the ECU measuring the deviation? Looking at photos of the PD Injector loom, it appears they are only 2 wire. So no metering. My suspicion is that it is measuring the time it takes one revolution of the crankshaft very accurately and correlating that with which injector just fired...

Bit of an update for anyone interested I think I've sorted problem. The engine in question is fitted to a T4 transporter. Which did not come with TDI as standard. It's a pretty common conversion to swap in an AHU/AFN. But you have to transfer quite a lot of bits off the the original TD block...

You are honestly mad, wanting to deck the block for the sake of it. I doubt your going to find any pistons that are going to fit the bill. You could offset grind your rod journal to the second repair stage to shorten your stroke. Most people do it to increase stroke. But I guess you could do...

I'm not convinced about off the shelf tunes like kerma and malone, When your doing a build like yours. I would talk to Kerma before your start and see what turbo they would recommend with their highest level off the shelf tune. I doubt it's going to be same as yours. So you may never see the...

I'll try some of them, Celtic tuning definitely weren't interested.

Before you build it, find someone who can tune it. Has been a real struggle finding someone in UK to custom tune my VE build. Hopefully will be better where you are. Plenty of people about who will flash a stage 1 tune on it. But soon as you tell them you have changed pump/nozzles/turbo. No...

If your rolling coal you need a remap,personally I would not hammer mod as it can be done in software when remapped and does not require hitting a precision piece of equipment with a hammer. However if your desperate it will probably cure surging at idle. Please note hammer mod and VCDS IQ...

So, put it all back together today. Seems to be running well. So have oil gauge on the housing now. When cold I had 72.5psi at idle When boiling hot I had 14.5 psi at idle at about 58psi over 4K The 14.5 does consern me because I have seen people say 20psi at idle. However there are no...

Thanks for the replys. I won't use RTV, I was on the fence about it really. Its such a shame I didn't have the gauge in the first place. Anyone got any rough pressures I should expect on the oil filter housing?
