Thanks.

They are standard 14mm "Bosch" type o-rings. Use plenty of silicone spray lube as you install. They fit super tight.

Yes, Lots of lube!

I thought i would carry on with this thread rather than starting another one...

Im currently building a 2332 turbo with CB quick tune EFI

I originally built by someone for me but it seized after a few mins... long story!!

Anyway, i am now building it back up again... here is a photo of the engine in the van just before it blew...


Here is a photo of it now...


Just waiting on my barrel spacers so i can sent my compression ratio

Whilst i wait for them to arrive, i have been working on getting my fuel and oil system in place and sorting through the rats nest of the wiring harness. Ive decided im going to 'hang' the harness from the top of the engine bay and drop the lines down to each of the sensors/injectors etc.

I know this pic isnt very clear... i was trying to be clever with my fish-eye lens attachment for my iPhone

any way, i though i would get some photos up of my plans/progress to get some different views... one thing i miss on the forums are photos of what people have done, so i hope mine can help those who are also interested/having difficulty planning theirs

will post more up after next weekend

Peace!

looking good, make sure to rotate your oil baffle 90 degrees clockwise

cool cheers... it was the old one anyway, i just chucked it on to reduce the risk of dropping something in

Engine all built and running... http://www.youtube.com/watch?v=_i9XBiHZWyo

Passed the MOT today as well so ive been able to (legally) take it off the drive.

Just got a slight problem between 1500 and 2500 revs when pulling away (more noticeable when going up hill). It seems to just die, pop and choke until the rpm picks back up again and then bang... boost kicks in and its off like a rocket!!

Im not too sure if its fueling or timing. Its right at the point of crossing over from 0-2psi where the timing starts to retard. Ive played around with the timing a little (+/- a few degrees) but i dont want to play too much until i really know what im doing :S

ive played around with the acceleration enrichment but it seems to make little/no difference to this 'dead' spot. Its also not improving the more i use it so im not convinced its a fuel issue.

Here is my spark table (the highlighted boxes in blue is the area im getting issues)


anyone got any ideas?

Peace!

[Devastator]

Sounds like a fuel problem to me. You might be able to find out for sure by setting all of the advance numbers, before and after boost, to 22. It won't make as much HP, but will let you find out if it's even a timing problem or not.

[Peace]

Yeah, good shout. I have been chatting to a few others as they also think its fuel.

looking at my VE Zones i have a large figure of 36.2% right in the area where im getting problems.


I might try locking this off and lowering it to 10-15% to see if it makes difference.

Im a little bit confused about why i dont have any figures in anything above 2300rpm... i may not have spent much time above there, but i would have thought it would have done something! :S

[Peace]

I know that screen print shows the CL EN (Closed Loop Enable) as off... but it hasnt always been like that... i was just playing around with it at the time of the screen shot

The zone that is at 36 can only go up to 39 , so I would save the file and apply the VE correction with the fuel map editor and reflash it to the ECU to start new.
Are You sure this it is not dipping into the other zones that have not adjusted yet when you get the stuble?
What is the A/R for that zone and the ones around it?

... Continued.

I have just finished the install of my Downs built 2160 2nd gen FI motor. Had a few hiccups and mishaps and false starts, but it's installed and running.

So I am a total noob to FI and am thinking, Now what? If it were traditional carbs and dizzy, I'd know the next steps. But it's blowing a bit of smoke and I'm reluctant to take it out for a run until that's sorted to my satisfaction. Can anyone direct me to a resource to get me up and running with this new system. As it is, I can plug in the laptop but I have no idea what kinds of figures I should be shooting for. Nor how ever to set the timing, for that matter, as it has a crank-triggered, coil-pack style distributor system. Unfortunately, the manual for the system is not yet finished ...

I just experimented yesterday with some different lubes for the injector o-rings. I had a super tight set to battle on. White lithium spray lube worked better than silicone or oil.

I decided to pull my CB Quicktune off and go back to dual 40 Webers. It has the ignition option. If anyone is interested, PM me.
