M135i, 197 turbo
I hope this isn't offensive bud, but I love how rough this thing looks lol
Just no messing around, straight in there and get the job done approach!
I know. Going to clean the throttle body and check intake system for leaks, and chuck a new crank sensor on as well. Other than that not sure what else I can do to sort the idle. Just sent a message to the bloke I bought it off as he claims it ran well, worse case is I'll go down the paypal route to try and get some cash back if the horrific noise from the top end doesn't go away as still assuming it's a stuck lifter.I wouldn't be whacking the throttle down until it's all running nicely pal... don't want another engine!
More slow progress as work is very busy. Cleaned the throttle body, changed the coils, checked for leaks, and seem to have a better idle.How's it going ?
Unsurprisingly Henk's customer service is crap. RS Tuning booked in for next Thursday. Pretty much finished now, just not comfortable that all is well with the engine :fearful:
Time to move all the tools out of the way and get it out of the garage :up:
Rs tuning would find it pretty quick! I bet it's to do with the ecuStill misfiring under load... this is getting annoying. So far we have a replacement 85k engine with good compression across all 4, timing is correct, new plugs, new coils, new TDC sensor and wiring, plus clean throttle body. Remaining suspects are failing fuel pump that can't supply enough under load, or injectors, or indeed damaged ECU. Just ordered an uprated pump from Engine Dynamics as I wanted one anyway, also going to check the resistance of the injectors to see if any stand out. Last will be getting the ECU checked.
Spoken with RS tuning this morning to move mapping back 3 weeks to give me time to get to the bottom of this, failing that they will investigate when I take it.
Yep going to, wanted to try just the pump first as that's £85ish vs £200 for the injectors and I wanted to uprate it anywayGet injectors swapped asap mate, my first point of call with my old 182 when it was misfiring.

They're the back up in 3 weeks when I've given up if nothing sorts itRs tuning would find it pretty quick! I bet it's to do with the ecu
Woooo, what sorted it mate?It lives:stig::car::spanner::up::smilingimp:
New higher flow fuel pump from engine dynamics. Also found a load of crap in the bottom of the fuel sender so cleaned that out. It's not perfect but it's 100% better and capable of driving. Going to send the ecu off for checking this week before we go for mapping.Woooo, what sorted it mate?
Good to hear mate, fuel pump was giving up then!New higher flow fuel pump from engine dynamics. Also found a load of crap in the bottom of the fuel sender so cleaned that out.

Got it out of the garage and cleaned off 2 months worth of dust and grime. Couple of bits left to do but nothing major. Going get some pics and vids hopefully in the next week
13th, going to plump for some 630cc injectors at the same time. Should make a little more power and more torque, plus running at lower duty cycleGood to hear mate, fuel pump was giving up then!
Now it should be a bit more capable and reliable.
Whens mapping?

I tune a lot of cars, a mechanically happy engine will not knock when running rich unless you've got an injector being held open and near hydrolocking the cylinder. If it's able to fire the mixture then it's not knocking due to being rich. It's worth checking you've got the fuel lines on the right way around though, dependant on how it's plumbed and what regulator you've got you COULD be running huge fuel pressure currently.
It could have a blocked cat/exhaust system, but I'd hope Paul would see those signs especially on a turbocharged car.
If it's not that then my guess is that the camshaft timing is overly advanced, this would cause cylinder pressures to be higher than normal. You'd have a really steady idle, great low down torque but it would run out of power up top. I see it all the time on various engines, I've got 2 booked in January to have their cams correctly dialled in... both with "professionally built" engines.
Do a compression check, but I'd seriously consider pulling the cams out and fitting a set from your old engine - you know then that there's nothing wrong and it gives you a chance to check the inside of the head for any issues too. If it's not fixed by that then it's got to be related to the engine control, but again Paul should see those signs.
Don't want to. Feels bloody quick on part throttle with all the torque and its running like crap. If I get this fixed and running stage 2 map it'll be mental.Don't give up!
@Matt555 Don't give up, that's the worse thing you could do, I had loads of problems when I did mine years back, but got it all sorted in the end.
Just take your time make sure you're 100% happy with the new engine and bits you are putting in.
You've done a great build so credit to you! it will be worth it in the end once you're boosting! (Y)
Fingers crossed for you mate!Righto. It's a sodding miracle, engine number 3 idles properly and seems to drive okay too....
Going to ring RS Tuning tomorrow and get booked back in.
Few other things to sort - need a new gear linkage cable as 1 is currently held in place on the gearbox with cable ties and araldite where the plastic collar has broken off. Rear passenger wheel is rubbing on the arch so need to roll the lip. All suspension needs raising 10mm ish and exhaust needs shortening by 50mm. Oh yeah, and oil change on engine number 3 :up:
