Mk7 2.2 - Acceleration issues after reconditioned engine

[metalworker0]

2013 didn't they have electronic actuators by then or you still on a vacuum one .

The vacuum pump also does the brakes ..so any fault with that you'd have hard brakes ..so if you have a vac operated actuator, if no trouble with the brakes , the fault would be in the actuator valve itself or the tubing or a non return valve in the tubing. if it was even that that was causing the trouble ,.

Electronic actuators on the EU5.

Back there in previous posts, he said DPF removed ..do you mean physically removed ..or just deleted from the software. 'cause, if its still there and blocked , it needs to go. how you hide it from an MOT inspection, i don't know.
and he said euro5 as well ....so he has an electronic actuator then .

Physically removed too, yes.
And yes i think I'm barking up the wrong tree with the vacuum pump. But I think I need a second opinion/smoke test on the vacuum system. Just find it weird that it's ok over 2000rpm (not perfect but ok) and it's the low revs that it struggles. Seems more like an electronic fault?

Someone has suggested I should check the clutch switch as it can affect the engine torque - preventing it from reaching the full capacity (and not going above 310nm).
Any experience of this?
Again I'm not sure if engine in my van has such a switch, so kind of relying on your guys' expertise.

Thank you so much

Yes your van will have clutch switch at pedal, if you press clutch in and press the go faster pedal full way down the engine shouldn't rev above 2800-3000rpm

EGR throttle valve operate together. The throttle valve closes as the EGR opens. The EGR opens as less/little power is required from the engine, no or little accelerator pedal movement towards high rpm, the vehicle has momentum - such as cruising on the motorway.
The 2012 2.2 has an electricaly powered NVT turbo controlled/monitored electronically. E5 Transits Sept 2011 to 2014.
The 2012 reverses up a slight hill with power - not touching the accelerator pedal. The 2012 needs some accelerator pedal movement about 1200 rpm to move forward up a slight hill.
The EGR and cooler has been removed.
When the MAP was cleaned was the small orrofice clear?
I tend to use the minimum accelerator pedal movement - minimum rpm required to move the vehicle.
Forscan readings at about 300 mtrs above sea level.

when does Map go to 160?

[tranmx2]

Without being pedantic; at about 2580 rpm.

i mean up the hill, down the hill or just cruising on flat road at 30kmh and 2nd gear?

Final update on this saga, and thank you ALL for your comments and suggestions over the last few months.

Clutch switch, accelerator pedal and vacuum system (smoke) all returned positive tests.

After considering the wear on the turbo and the fact a con rod snapped in the old engine (plus the dpf had been previously drilled out), mechanic has concluded that there was very likely a dodgy map in the ECU that was asking too much of the engine, which was probably deleted when the learns were done for the new engine or that the ECU was reset and deleted the remap. I had just got used to that excess of HP and torque as being normal, when in fact it was over-performing.

The van does run excellently now. But it is a van after all and a mk7 transit at that, so expectations for engine performance need that consideration. It's my first transit though, so wasn't to know... until now.

Glad to know that it wasn't an actual problem you were experiencing after having the original engine going kaput.

You can get the Euro5 engines mapped upto 155ps as that's a standard Ford map for these engines and Ford themselves sold them as a power option. Should be a decent compromise with safety/longevity in mind.

I'd fully recommend Vantuner (martynx on the forum). He remapped my little connect years ago and it lasted a few years of abuse by me (i was younger then) before the fuel pump threw a wobbly and made me scrap the van.
