But it ain't standard ride height, it is at least -60 and about 12mm off the original bump stops all round. With sach HDs it doesn't crash or bang, the ride is good and it'll still handle plus I don't have to drive like a pussy when the road is any less than billiard table smooth. Sausages mate was reduced to 15mph on the drive up to his workshop - I could cycle it quicker than that.
Those steels do leave far too much arch gap.
Originally posted by Activ8Is that with the new N75?
Got to see what the those sensors are reading Reg. 10psi = 0.68bar = a semi.
Did you cap the top port on the actuator?
I'll do a log run, pull the timing back towards 55
Didn't cap the top port, it's not going to make that much difference, but I'll do it
Those stanadynes days are numbered, reckon the balance of fuelling is all to cock, can't see how this will make that much difference either..
I think a sensor is throwing a curve ball in somewhere - guess the log run will give the answers.
Time to google how to do a log run and how to interpret it.

Have you code read the van?

Have the injectors started to clean up?

You Maverick!!! might be starting a new trend and a price hike!

Originally posted by Activ8 View PostIt's not smoking is it? So there's enough air coming through. So you're either not making the pressure, loosing the pressure, or being restricted in making it. Can you drive over 3000rpm?
Must be capable of making pressure as this is second turbo to give exactly the same results
Not loosing pressure that I can tell
Possibly restricted in making it - fuel?
Can drive over 3000 rpm no bother - no top end urge but it'll rev out quite happy and pull three figures

Originally posted by regcheeseman View PostDunno, duty cycle at idle was pretty high, 80% ish IIRC
Originally posted by regcheeseman View Postyep - just a odd eeprom error code

Originally posted by regcheeseman View PostNot obviously - if anything, starting is worse with new turbo, taking 1-2 seconds to fire - a decent indirect engine would be instant
Can you do some screen prints of the engine channels. Ch 0 gives all the basics , switch to basic settings column 2 for the true timing number. (If at fuel temp).

Originally posted by regcheeseman View PostNope, checked - a few maps, some interesting stanadyne stuff that's unfortunately worthless as trying to convince anyone will be fighting against the accepted internet 'wisdom' - which only has one acceptable source (much like everything in the T4 scene, known as the 'PP Tuning exhaust syndrome'. )

Originally posted by Activ8 View PostWe'll see if you run the logs. VCDS Engine Ch 8 shows fuel.

Originally posted by Activ8 View PostJust want to help Reg..
Could have taken a log run today as I found myself on a dual carriageway, tried WOT in fourth but I was nearly 30 mph over the posted limit so had to back off around 4500, but it was still pulling, albeit reluctantly - feels like fuel to me.
Ironic if the pump needs a rebuild!Last edited by regcheeseman; 30 December 2017, 11:41 PM.

Just like you must feel, I just want it sorted too....
Think you've got to rule out the sensors first.
I'm finding some of the symptoms really odd.... if the turbo doesn't make the boost targets the ECU assumes a fault and throws it into limp mode. With the remap that's still fine and will drive +5-10% over standard. I'm assuming that is what's happening?
Your last VCDS on all 5 injectors showed poor injector tolerances but still only +/- 1-1.5mg/s from
requested. If the pump pressures were low wouldn't they be weeping more and showing a greater tolerance spread and resulting in tons of smoke?

It's not going into limp though. If the ECU believes the boost is there from a duff sensor it'll overfuel and smoke, but it isn't.
I'm wondering if there's an issue with driver request?
