Haltech Installation Issues

Maybe the sensor is bad?

Also, maybe you could install some kind of check valve so that it would bleed off air as soon as it hit boost or something.

You could also try running it off a seprate line.

Have you tried bypassing the stock MAP sensor alltogether? I see from your pictures that you still have it connected to the vaccum line from the white T. For the hiboost installation of the F10 you need to bypass the stock MAP so what i did was removed both vac lines and connected them together.
pix please. my brother and I are trying to figure out who's saying what and what is the right way here. after looking at all the pictures I posted Juan has yet to tell me that way we did it is wrong, only that he seems to think I am boosting over 1 bar and just lying about it, lol (silly) so far Juan, SPD, BEGi, you, Jared and Dana have thier own theories and none of them match up lol.

i am eager to see yours, as you say it works and that in the end is what matters to me :)

the two pronged device to my understanding was a check valve. i was thinking about seperate lines but i am being told doing that will make no difference.
 
Sorry... mistake the prong that is connected to intake mani i removed and it is now connected to my boost gauge so my stock MAP sensor isn't connected to any vac lines. Can post a pic if you like

Give this a try...

thats what I thought, the stock Map sensor doesnt do s***
Juan is saying it needs to see boost so the ecu can pull timing, my thought on that is, if the ecu can retard timing based on boost if the vaccume valve is bypassed, then why does the MSP have the same setup

the vaccume valve prevents the stock map sensor from seeing boost, if I remember correctly, a while ago there were some choice idiots that tried running 16psi on their stock mazdaspeeds, at that point, IF the stock map sensor was a fucntional unit in the tuning of the car, those cars should have had a check engine light
that and why wouldnt mazda take use of that feature from the factory?

weather it is disconnected from vaccume all together or hooked back up the way it was stock, it will get rid of the CEL
my only thought is that it might have somthing to do with the way the car idles, thats why I think it should be hooked back up the way it was stock

It might not, but it's an easy test.
 
Ken, try running the car with the map sensor disconnected from any boost/vacuum source. All cars running with haltech with or without the sensor bypassed are not throwing a CEL unless they go above 1 bar.
 
I would be willing to bet $50 that if ANYBODY with a turbo protege including the MSP had the stock MAP sensor setup the way Ken had it, they will get a check engine light as soon as they hit boost
 
Well, totally bypassed the MAP sensor and drove around for a bit, hit some boost, watched my AFRs on the AEM etc etc, in boost and at 6 psi looked to stick around mid 12s. After I left boost I was driving down the street for about thirty seconds when the CEL started blinking on and off, then stayed on. I ran the code and it came up as Cylinder Number Two, Cylinder Misfire Can't say I like those kind of CELs.

Going into boost the car seems to run a little lean up to about 1 or 2 psi. Spark plugs perhaps? Fuel map? What values/correction factors am I supposed to be looking at?

I cleared the code and the car doesn't run any differently, I didn't hear any knock :( uh, help?
 
juan/jared - the fuel map measures in kilopascals along the bottom, correct? I am trying to convert it to psi so I have a better idea of where I am adding/pulling fuel. I gave the haltech map sensor its own direct source and reconnected the map sensor and check valve the way it was when I was using the fuel pressure regulator. I can only assume that since the car ran fine with it left alone using the FPR that it will do the same with the haltech. Also, my brother and I checked the spark plug gap and found it to be set at .045 (shocked) that could make a big difference!

omfg .045 ... WHY?
what is the gap on the mazdaspeed protege plugs?

aric and I drove around for an hour. no detonation, we went through the fuel map and linearized/added fuel at the lower psi levels of boost where it was running AFRs of mid to high 13s. we think we've got 90% of the map nailed down where we want it, possibly too rich in some areas. the car would stumble a little on coasting/no throttle applied and it would peg AEM gauge pig-rich. I imagine the Haltech is just mapped to idle very rich. I can't see why the map would be set to have the car idle/coat at a ratio of 11:1 or richer though, why not around 14 in the stoichometric range? there was a point in the rpm range where it still ran 13:1 under partial boost. We also didn't play too much with the rpm ranges between 5500 and 6500. But the car pulls pretty damn strong under full boost and full throttle, no check engine lights, no misfires and this is with the stock map sensor setup as it was from the factory.

i will try and post screenshots of the fuel map later today.

I believe the factory gap on the Mazdaspeed plugs is .030-.032

If I recall correctly, Juan gapped my plugs to .028, need to double check them though.

As far as the unit of measurement I believe you are right, the Fuel map "y" value is Load measured in kpa.

just so everyone is clear as Juan said this may have been worded confusingly - i am NOT still using the BEGi FPR. To clarify, when I was using the FPR as the fuel control device, I was not required to screw around with the stock MAP sensor. Now that the Haltech is the fuel controller, I don't see why the stock MAP sensor would need to be altered if the FPR was not conflicting with it.

stock MAP sensor on a P5?? or do you mean MAP sensor included with the BEGi kit??
there is no map sensor with the BEGi kit. the car has a stock map sensor near the strut bar on the passenger side. with the begi kit you leave the stock map sensor alone. with the hiboost kit you bypass the stock map sensor. i have yet to under stand where the difference lies.
