I'm sure I may have read on another thread that the old shed is up and running again... any shance of an update/piccies?

Oh and congrats!!

Nope - you didn't read it on another thread......

However - last night - IT LIVES!!!!!

Long and short of it is that the idle screw was set to let too much air in. My previous engine (that the TB's came off) had pretty lumpy cams and needed a pile of air to idle. Supposedly the DTH TB's are really touchy about idle setting (as you've got 4 throttles instead of one, so a wee turn makes a big difference) One turn on the screw would have been enough that the engine would never even try to fire as the mixture would have been far too lean.

Supposedly, it would have been really difficult to see the injectors firing anyway - proven by looking at them, after we confirmed the engine does fire. Because they are running sequentially (one cylinder at a time) as opposed to batch firing (every one goes when each cylinder needs a pulse) you have to wait a relative fortnight between pulses and the pulse only lasts for 14ms.

Anyway - we just need to finish the brakes now and replace the rear clam and she's back on the road. The revised cooling system worked fine (if a little hot before the stat opened) but we'll let it settle before thinking it's a fault. Probably more the temp senders than the stat, as we're only talking 8 or so degrees - importantly, though no leaks or airlocks when up to temp. The fuel map was way lean - but some of that will be accounted for by the TB throats being unfiltered when we tried it. I'll get the airbox back on and just shift the whole map with the Emerald's injector scaling function. It should then be ballpark.

Am I a happy bunny or what

Oh, got video last night, but it's some weird camera format, so I'll try uploading it to Google Video and see what they say to it...

I'll also update photos (which are on the home computer) with the last few efforts (including Robin's visit)

TBH, the only reason it's taken soo bloody long as the car is an hours drive away & I've had to co-ordinate free nights with Hambo.

All told, I've probably only spent 3 or 4 decent days on it in total (hours-wise).

Nice work Shug - you don't fancy helping me sort out my spaghetti for wiring ..

You doing Mexitowers?

Dinna talk to me about wiring.... I'm expecting 'nam style flashbacks

Not at the MT trackday (w*rking

) but will be doing the rest of the weekend.

Congrats!

If it's running lean that may be the reason for the increase in heat no? I have no real clue just a thought.

Didn't have time for that to be a factor - 'twas just a bit long for the stat to open, initially. Like I say - it's not concerning me overly as the temp variance could easily have been accounted for by the stat lying about for 4 months, or the sensors being a bit out. It all works though and the stat (gradually, for that is how it's designed) cycles properly.

Can't wait to drive the bloody thing now!

You'll be missing out on some tasty 993 GT2 pax rides...

Sure you can't get the day off?

Definately - it's a charity fashion show that we're producing. If I ain't there, it doesn't happen and as much as I don't give a sh*t, I don't need my P45 ATM.......
