well i finally got round to logging it tonight. after over 2 weeks of playing with vagsuite i decided to remap my car via mpps.. still the same problem so that rules any hybrid / fmic issues lol. a few screenshots below, i think the problem is the n75 as the duty cycle doesn't look right Tuesday,05,July,2016,22:04:25 038 906 019 LA,,1.9l R4 EDC 0400SG 5266, ,Group A:,'011,,,,Group B:,'013,,,,Group C:,'008 ,,Engine speed,Spec. intake press.,Actual intake press.,D.cycle MAP,,Cyl 1,Cyl 2,Cyl 3,Cyl 4,,Engine speed,IQ driver's req,IQ via rpm(Torq),IQ via MAF ,TIME,2850-3150,2200-2400,2100-2600,35-80%,TIME,-2.8 to +2.8 mg/H,-2.8 to +2.8 mg/H,-2.8 to +2.8 mg/H,-2.8 to +2.8 mg/H,TIME,2850-3150,65-70,47-51,47-60 Marker,STAMP, /min,,, %,STAMP, mg/str, mg/str, mg/str, mg/str,STAMP, /min, mg/str, mg/str, mg/str ,0.72,1869,2436.0,1740.0,34.7,0.00,-0.54,0.54,-0.47,0.45,0.36,1827,69.7,70.0,70.0 ,1.80,2100,2520.0,2424.0,46.2,1.08,-0.54,0.54,-0.47,0.45,1.44,2037,69.7,70.0,70.0 ,2.88,2373,2544.0,2712.0,57.4,2.16,-0.54,0.54,-0.47,0.45,2.52,2268,69.7,70.0,70.0 ,3.96,2625,2556.0,2880.0,68.5,3.24,-0.54,0.54,-0.47,0.45,3.60,2541,69.7,70.0,70.0 ,5.04,2877,2556.0,2880.0,74.1,4.32,-0.54,0.54,-0.47,0.45,4.68,2814,69.7,70.0,70.0 ,6.12,3108,2556.0,2832.0,78.9,5.40,-0.54,0.54,-0.47,0.45,5.76,3045,69.7,70.0,70.0 ,7.20,3339,2556.0,2700.0,79.7,6.48,-0.54,0.54,-0.47,0.45,6.84,3255,69.7,70.0,70.0 ,8.28,3549,2556.0,2700.0,83.3,7.56,-0.54,0.54,-0.47,0.45,7.92,3486,69.7,70.0,70.0 ,9.36,3759,2556.0,2736.0,87.7,8.64,-0.54,0.54,-0.47,0.45,9.00,3675,69.7,70.0,70.0 ,10.44,3948,2532.0,2736.0,91.6,9.72,-0.54,0.54,-0.47,0.45,10.08,3885,69.7,70.0,70.0 ,11.52,4116,2496.0,2712.0,94.0,10.80,-0.54,0.54,-0.47,0.45,11.16,4074,69.5,70.0,70.0

The amount I have spent on this car is unreal, money and many hours working in it.. I feel like throwing petrol all over it.. Anyway my water pump has a slight leak so I'm gonna change the pump and timing belt maybe next week. While that's off I mayaswell throw a new camshaft and lifters and injector loom in. When that's done everything has been changed.. it's gonna have one lucky New owner when it gets sold haha...Anyway I'll report back in a few week when iv sorted it.

thanks for the reply, the sensor was bought on sunday from euro car parts, its a genuine bosh sensor. i have about 4 map sensors in total sat in my glove box, 1 is faulty and the other 3 are working fine, well working the same as my new one is.. im thinking of removing the fmic and and checking all the welds cause somethings causing the black smoke and low power.. and i only get black smoke if i nail the throttle, i could be cruising at 30mph if i press the throttle to the floor for a split second you see all black smoke in the mirror. and thats in any gear or parked up in neutral .. do these have a throttle position sensor ?

the ecu has been un touched, the car is standard i believe. when i changed to my 3 bar map sensor last month it was pulling like a train then it just suddenly lost power one day and its been like that ever since.

try with the downpipe of first, unbolt the 3 x 12 or 13mm bolts and let it hang and take it for a blast

a few pics from last week from vcds any idea why the boost readings are higher from a 2.5 map than a 3?

Still no joy :( I have checked with vcds and nothing. If I use a 2.5 bar map sensor it pulls better. I have splashed out another 50 quid for another 3 barmap map sensor and it pulls terrible with loads of black smoke. I have no boost leaks as I have checked with vcds with measuring block 11 while I squirt some fairy liquid all over the joints. Why would.it.run better with a 2.5 map senaor ?? anyway the guy who made my intercooler has extended my map sensor wires so I tested pin 1 and 3 wich read 5volts with the.ignition on. Does anyone know when the engine is running if I should be getting 1.7 volts as that's what it shows in autodata for pins 1 and 3 as 2 and 4 are the ait sensor.. many thanks

Yeah I'm on a standard map with a hybrid,fmic, stright though exhaust and an egr delete. I think it's pointless untill I get some power back or I'll throwing even more money away. Anyway I'll check everything tomorrow on vcds see how things look.

Thanks for the reply.. since owning the car it's always had low power even before the turbo change. I figured out it had the 110bhp intercooler and map sensor fitted with the big probe about 5 months ago. So I had to bodge the intercooler insert with A rubber innertube as boost was blowing right out with the new small probe sensor fittee .. anyway so problem was solved then by replacing to the correct map senaor, then a few days later poof all power gone.. and it's been like this for about 4 months.. I finally have my lappy back so installing vcds atm getting ready for tomorrow morning.. I have noticed the turbo doesn't seem to be opening up correctly as it's really more of deep sound rather than the nice turbo whistle i hear from the exhaust. tomorrow's job removing all pvc and vacuum pipes because that deep turbo sounds like the vanes are not fully opening, so could be either vacuum solenoid or pipes I'm thinking.

The cars not been mapped yet. And I'm awaiting for my laptop to return from the repair shop as the ribbon went on the monitor. I'm currently using torque pro atm with no faults, I do hold a full version of vcds.

In the past month if spent lots, a new gearbox "jnc" with a new clutch and flywheel. Then surprise suprise my turbo split in two parts and blew from the aluminium side so I then got a decat and upgraded to.a pd160 hybrid turbo "180".. car still ran the same black smoke and lacking in the torque and and not the power side.. I then bought a brand new bosh maf and map sensor, Problem still the same.. I then decided this week to get a custom fmic built what took around 3 days.. guess what problems still there with all hard pipe work fitted with about 4 silicone joints fitted... it's driving me mad.. Also used 1.5 litres of diesel purge today just incase lol.. anyway things I have noticed today.. vaccum from the tandem pump is good.it's showing around 28inhg with the engine on idle.. fault I have found today lies with the vaccum system im pretty sure that the vacuum reservoir should hold vacuum over night? Well I'm switching my engine of and leaving it for about 5 mins and it's empty .. could this cause black smoke caused by a vacuum problem?

Bench test results

Anyway all sorted, New hybrid pd160 turbo

Thanks for the reply, i changed the oil feed pipe 3 months ago as the old one was leaking, I'm just thinking if the oil is circulating properley before i fit the new turbo. I'm guess without the turbo fitted to the car I can crank the engine to see if the oil is flowing from the oil feed pipe.. tomorrow's job is cleaning all pipework/intercooler, and changing the oil and filter.. don't fancy blowing 400 quid up

edit: sorry half of my post is missing.Could this be an oil seal.what's gone? The exhaust side of the turbo is really stiff with lots of resistance and it's.scraping against the housing. I'm just aftwr finding a possible cause before fitting a new hybrid turbo on the weekend so I wouldn't like it go bang after its been Installed

As above my turbo blew Saturday evening while shifting in to 2nd around 20mph, at first I though it was a boost pipe but the tell tail sign was white smoke coming from the engine bay and the engine was stuggling to breath.. anyway I got round to removing it today only took an hour and the cold side of the turbo was completely broken off, no sign of any impella fragments anywere,so hopefully it flew on the road
