New Install - 1st start

Post by katana »

Hi all - at last my Escort RS2000 Zetec is nearly complete so hooked up the lappy to check the diagnostics and everything seemed to sync up ok and I managed to capture a crank oscilloscope screen and attach it below - does it look ok or anything jump out as needs looking at ?

I'll attach the saved map as well for comments although this is essentially the 'stock' DTA map.

The engine attempts to start, starts but quickly dies. Unfortunately I don't have a working fuel pressure gauge and a Bosch adjustable regulator (although what pressure its producing ??? - if at all !) A gauge is to be sourced to answer that question.

Quick run down of the engine spec. - 2.0L Blacktop Zetec, 45mm Jenvey 'DCOE' type throttle bodies, 4No COP's, std. cams and did want to use a idle air valve and did wire one but it doesn't seem to be doing anything ?

Whilst i'm eager to get it working - its taken 8 years to get thus far so another week or so ain't gonna hurt but any responses in the meantime would be of assistance.

log it.

does diag screen suggest any crank or cam errors when it starts or stops ?

Scope looks fine.

Presumably you are using the cam sensor ? are coils configured as such ? Injection ?

Try it as crank only instead ?

Crank sensor is wired backwards. Otherwise looks good.

Great, that's what I needed confirming - I couldn't tell for definite. Ah well - little bit or rewiring . . . . again :lol: :lol:

Hooray - that made a difference - thanks Alex! Took a bit of cranking but it started, it ran, got hot and noisy and smelly . . . . .and it puked oil out of the dipstick - I guess a bit too much oil DOH! One thing that was a bit puzzling - I reset the TPS, closed #46 odd and open #840 odd but when running the 'Real Time Mapping screen has the active cell up on the TPS 95% columns and it drops to the low end when throttle is applied? Doesn't seem right?

I'm pretty new to all this and a little overwhelmed with all the various screens - not knowing what to look at or adjust if anything at all? Idle rpm was nice at just over 1100rpm then after fiddling with the TPS to get the get the figures in the right end of the scale, idle is pinned at around 2500 with slack in the throttle and throttle blades backed right off ?

Does the IAV do anything as my seems to click with ignition on and a few clicks when ignition goes off ? Strange as I thought it would 'buzz' and then get slower and then stop so not admitting air - confusing?

I guess i'm a bit out of my depth - tuning these things isn't as easy as I first thought and I thought carbs were tricky!

Oooh - almost forgot . . . . . anyone in the Hants / Berks / Surrey area that can do DTA set up / tuning / RR dyno?

Sounds like the TPS is failing and using the default value.

Try Gareth at Autologik in Guildford.

Carbs are a nightmare, taking things apart and getting fuel everywhere....a laptop is soooo much easier.

You initially said TPS was not reading correctly, then later you did...is that aspect resolved ?

Just watch TPS readings 0-100% and see if they are smooth and repeatable, and that your foot is indeed fully off the pedal and blade fully closed when 0 is set, and likewise the blade is fully open when 100% is set, and cannot move beyond that point.

Ok - you could be on to something there as I think the TPS default is set at 95% ? I guess I buy another one if only for elimination purposes.
Thanks for Autologik - that's close enough. I'll give them a call in the future.

Test...dont throw parts at random.

Firstly the TPS read correctly ie. closed low number, open high number. Then I noticed the active cell @ 95% on idle and reducing with throttle application so although the throttle stops screen said everything was correct I thought the two were related so swapped the TPS around - that gave high # closed and low # at WOT - so wrong. Then tried the pins - swapped those around - same result, also tried the TPS reverser - same result ! Back to start and the TPS screen shows low # closed and high # at WOT. DTA tolerances for end of the POT tracks are quite narrow as a couple of times the closed end was below 40 and open was above 950 and the ECU was warning #'s must be above and below respectively.

Moved all the carpet out of the way so pedal movement isn't restricted - closed is closed and open is open.

The TPS seems to give the right 'sweep' readings but the 95% thing is confusing! Its a Culven type from Jenvey - it seems a bit 'sloppy & loose' although it was new its been on and off a few times - any recommendations for alternatives having a D profile hole?
