Update: it officially runs! But I'm not out of the woods yet.

Whilst the engine is now indeed running, it's not as smooth as it could be. It sounds quite clattery down the bottom, but John at SC sent me videos of it on the dyno and it's smooth as silk.

It also struggles to rev when I'm gentle with the throttle. If I give it the beans then it revs up just fine. But if I just tap the throttle very lightly a few times, then it starts to cough and splutter, and I have to give it more to stop it from dying.

The plugs are also completely black each time I check them. I've questioned John about the possibility of the Injectors being too big, but he assures me that the plugs will clean up once it comes off the cold start enrichment. I'm tempted to try some smaller injectors, but I have no idea where to source these or if they'd even be a direct swap.

So this is where I am currently. I'd love to keep this going and get more opinions from those more knowledgeable than me.

Cheers
Chris

I'm glad you've got it running, but if it was " like a Swiss watch" on the dyno it should be the same now, but, have you tried just starting it up and letting it tick over for at least 30 seconds most of these systems have an automatic choke system if you like that runs the engine rich then reverts to the normal map, after which it should rev cleanly etc. You can tell when this happens as the revs drop to a normal tick over. If the car runs well enough at the moment to drive it and you are close enough, get it booked into ATSpeed in Rayleigh for the sake of a couple of hundred quid they will save you hours if not days of agro and guessing.

That's what I thought, doesn't make a lot of sense. I actually let it idle for about 5 minutes yesterday, and while the revs did drop, it didn't really get any smoother.

I think you're right. The next step for me is to get the car on the road and over to ATSpeed, as I've not got much left to do. Hoping I can limp it through an MOT.

Book ATspeed in the morning and MOT in the afternoon like that IF the plod stop you, you can tell them you are driving to the MOT😁

Good plan!! Do they do MOTs at ATSpeed?

I don't think so but they are on the edge of the industrial estate, so no doubt know a company that does, I'm saying go to ATspeed as for some reason I think your in that part of Essex, if not I know a couple more in the county

Ah right I see, I'm actually further north Essex, just south of Cambridge. Rayleigh is about an hour from me which is still manageable if it's the closest.

I've been out tinkering again today. I have discovered that the engine gets worse as I warms up. When I first started it cold it wasn't too bad, and I could blip the throttle without it coughing.

I idled it for about 10 minutes or so, giving it the occasional rev, and as the engine warmed up, it became much harder to control the throttle. Even if I tried to hold it at a constant 2krpm, the revs were still jumping up and down without me doing anything. And then half the time it would die as soon as I let the revs drop. I'm worried I may not be able to drive it to be tuned if I can't improve it at least a little bit.

Very worried about causing damage so I dare not run it any longer while it's not happy. After 10 mins the temp guage still read stone cold, so I'm guessing thats knackered too...

Try Revivals 01763 208043 they are based in Royston, which should be a lot closer and are mini people

Ahh I've actually been to revivals quite a lot haha. Great guys, I go there for my MOT every year. I always figured that they would be too 'old school' for this sort of tech? And does it not matter if they're not a specialist in SCS Delta ECUs? Either way I'll give them a call and see what they say.

I find it hard to understand if it runs perfectly in the dyno it doesnt for you.
I am cynical and dont trust anyone so straight away I think SC are being shady.
Or. What's different. Petrol new? Pump pressure good? Anything else that they would have set up on the dyno that you wouldnt
Rgds injectors I heard they run like **** if they are bigger than 220?

I hear what you're saying, but I've seen the videos with my own eyes. I agree though it is definitely something to be concerned about. The fuel is literally brand new, and it's the good high octane stuff. Fuel pressure is spot on too. I may pick up some 220 injectors just for the sake of it.

Chris, did SC write the MAP for your ECU and was that what they used on the dyno??

No clue mate, I was under the impression that the ECU was an off the shelf part with a map pre-loaded onto it. I'm currently chatting with John on messenger so I'll ask him to clarify.
