    4HP22EH Valve Body Service Guide

    I've rebuilt lots of different auto boxes and am pretty well equipped to do it. Normally I've been able to find an ATSG manual or similar for the different boxes. I have found the rebuild manual for the main box and for various other variants of the valve body (BMW, Jaguar etc) but not one for...

    Currently waiting for the ECU to come back from a remap - it's an MSB so chip change needed. In terms of where I got to it pulls ok to about 3k rpm, after that it's flat as anything and takes an age to pick up speed and rpm. It will rev out, eventually. Boost and air flow shows ok. I had to...

    Throttle pedal position sensor is working fine according to Hawkeye. I found the throttle had been set to 3 track in the ECU, not sure why and reset it to 2. Not that it made any difference. Crank sensor is about the only thing i haven't touched/changed.

    Whats the straw that broke the camels back? Auto box fill plug is rounded out (not by me). While it might seem minor, I not sure that I can be bothered with this any more. And I know it needs some serious rust repairs (bulkhead) before the next MOT. I just wanted to get it running right before...

    Yes, stall test still 2200-2300rpm. And can confirm injector clearances set as suggested.

    I have it running up to 230kPa MAP/130kPa boost, with 5 threads showing on the wastegate. I'll check the roughness again tomorrow but remember seeing 2-3rpm on each cylinder when I scrolled through yesterday. I'll grab the ECU number tomorrow, but I do know it starts MSB

    Yes but to get the boost I had to wind the wastgate actuator in way more than I should. Limiting the amount the wastegate opens quite a lot more than is normal to get the same level of boost, or gas flowing through the turbine side with less being bypassed. To me that points to issues there...

    If i was certain a different turbo would fix it then I'd splash a bit more cash. But frankly I'm 100s of quid and 4 solid days into chasing my tail with it now and ultimately I need to decide what to do with it and how much more to throw at it. I think sierrafery mentioned about exhaust...

    I'm close to giving up with this now. Swapped on the new wastegate actuator. Even with it wound right in max MAP was 180kPa, so that was a waste of money. With the original fitted max MAP is back to 215-220 with 10 threads showing. Tightened it up to 5 threads showing and got over boost...

    Ordered a new one to try.

    I just tightened it another 1.5 turns. Now 9 threads showing and still only see 215kPa. Connecting the wastegate directly to the boost hose, bypassing the modulator, I only get 208kPa with the same wastegate setting. No visible signs of leaks at the exhaust manifold (sooting). Going to try...

    I did tighten the wastegate 2 turns. Checked boost again this morning, still 215kPa. Checked injector clearances, all were correct Finished replacing the intercooler hoses all originals were OK and not delaminated. Steel pipe in good condition, looks like it was recently replaced. Clamped...

    I'll try that tomorrow. I say its boosting as I am seeing 215kPa MAP on the Hawkeye live data at max load

    I will check them tomorrow. The old pump was clean when removed. All the hose clips are OK, and it is boosting to the correct pressure.

    It's on standard size tyres on 17" rims. As far as the exhaust goes, it has no cat (being EU2) and the rest looks ok, at least from the outside. I've replaced the intercooler to EGR delete hose when I did the delete, but I haven't done the others yet, but that one was in good condition. I am...
