What are you going to run for engine management?

Rallies are no place for traitors

Yes but it is not the only rally car I have owned. My hate of gadges comes from my 323GTX with turbo boost, EGT, Mixture, Water Temp, Oil Pressure, Voltage, Oil Temp and likely some more.

So I go into the last stage of a rally in I think 2nd place in some novice class a few seconds down on 1st. About half way though I see the boost and oil temp looking odd, I spend some time looking at them to see if there is a problem since I had lost a few turbos on this car. Rather then driving the car I start to diagnose it. The results are inconclusive, with the demands of the stage I can not tell if the readings are a problem or not. Finally I decide to not worry and get back on the pace.

Finish the stage and find I droped 30 seconds and down to 4th in class, I ran the stage slower than I had the time before - that never happens I always impove my times. Once back on the transit, everything reads right... there was never a problem.

Two years later I finally understood, there is no point in gadges cause I am never going to stop or Trouble-shoot ever again on stage unless the car stops going.

In the long run reality always wins.

I'm wondering why the switch for the pumps? Other than that's how Ford did it. Pressure is regulated, so why not run both all the time?

If I had to take a shot at this, it's because one's a spare in case the primary one is clogged with crap or breaks down. That's the conclusion I guessed, since mine are labeled "Fuel pump" and "Aux. Fuel Pump" under the respective toggle switches on my dash/console.

Proper guess ?

Ramada 05, after a crappy day 1 Cem and I decide to let it lose. Diamond Creek Out, 3 miles to end of stage, oil pressure starts dropping, even though the engine is running normal, 200 yards from the tree/water spot, oil pressure is down to 15, panic in the car, I have the video. We pull over. I am trying to diagnose wtf from the cabin, oooooops, Coralba flickering, none of the OEM gauges are working, map light kaput aswell. You can hear me yell in Klingon (I think that was it) " Electrical, Keep Going ". We continue but now we are both spooked, I'm reading with one eye on gauges he's driving with one eye on gauges. We lose a little over 45 seconds but still make decent time.

Vermont installed the Oil Pressure Gauge on the same circuit as the OEM one, duuuuh, something tripped the dash fuse and we lost all gauges. We replace it in service, second to last stage, it blows again, now the fuse I put blows immediately, 10 miles from the finish of last stage we DNF due to an alternator problem, or so we thought.

Moral of the story, too many gauges are like too mant mirrors around a woman, they will either cost you $$$ or make you time.

And now the rest of the story;

A month after Ramada, the dash is out the wiring harness is being inspected wire by wire, there is nothing wrong, but the car is still not charging, knee deep in frustration. A visiting Turk chimes in, 15 minutes later we have the culprit, a fried DCCD harness that looks fine from the outside but the wires shorted from the center of the bundle when they got heated by the catatonic complexer.Once it was fixed everything was bach to normal. Subarus need the dash-DCCD Computer-DCCD trio to work at all times, if not, well the DCCD is out and God knows what kind of torque split you have and more importantly the car does not charge. Stupid eh ?

I understand that Morton, but if both pumps feed the same line and regulator, why the switch? Look at it this way, if one pump is running you get say 40 psi fuel pressure, if both pumps are running you still get 40 psi fuel pressure. If one pump dies you still have 40 psi fuel pressure.

But then you're running one pump unnecessarily. If a pump has a finite working life before failure, no sense leaving them both up to chance.

OK all you guys hate gauges....

The boobies told me to do it!!!! ARgh

I have done this Skye. I actually pulled my oil pressure sensor out, put in a pipe plug and got a -6 to npt adapter and mounted the actual OP sender onto a free-but-previously-capped -6 fitting on my FPR.

This is when I was having a lot of trouble with my new turbo engine installation and wanted to check fuel delivery. Ran it. Logged it with a note that OP actually = FP on that run.

Motec engineer suggested it. I'd say its fair game.

For good sensors, go to the Motec website, download the catalog, see what they use (usually a Delco or Bosch unit) get the part number and order it from your auto parts store.

Party on.

Hey Lurchie, you seem to get the drift with what we're up to.
As all these boys are rank (phew) beginners, none are supposed to be having any evil thoiughts of more power so all we've done on the motor side is use the Garrett T3 of Ford Cossies, added a 2wd Cossie intercooler and that's that.
Now IF we check and see AFR being somewhat wacky cause of how the turbo and intercooler work and we have the standard EEEEK! IV management then the only thing we have to putz with is the COSSIE ADJUSTABLE FUEL PRESSURE REGULATOR, so we sorta want to be able to see where we are.

Yeah getting Bosh senders is nice or all Krautski stuff as they invariably have their range stamped on the hex.

Right on, John. Another trick I did on the VW for wacky enrichment was to put a potentiometer on the dash wired to the coolant temp sensor. Don't know if the Ford EEC adds fuel for warm up, but if they do, you could do that too for a bit more fuel.

The Protege originally used an EEC V and I had to add an adjus. fpr on that, too.

You know guys on eBay sell coolant temp sensor resistors for a million dollars on eBay for "big HP gains" hahahah

Radio shack. 5 bux. Potentiometer so its tuneable.

ebay sucks.
