Haltech Installation Issues

[HiBoost TS]

we went through the RPM ranges and selected all bars and added fuel. we're getting better numbers into boost now, but we have a real basic question using halwin. how are we sure that we are saving the changes to the haltech unit itself?

we read the check engine light with scantool. the code is "manifold absolute pressure sensor error/high voltage". it went on again as soon as we went into boost. the stock MAP sensor is obviously seeing boost and throwing a CEL. we're all scratching our heads as we thought we bypassed it properly.

juan, go ahead and call me anytime this week between 9am and 2pm central standard time.

First, if you are doing the changes to the maping online, I mean while the engine is running, the changes are done and saved to the Haltech ECU inmediatelly, but you need to save the new map into your computer. Go alt+F and then click save map. Give it a name and that's it.

How much boost are you running? The stock Map sensor won't trow a CEL unless it is over 16 psi of boost.

i have never run over 7 psi of boost on the car and when test running the car I did not go over 5 psi. Can you post/send me a picture of how your stock MAP sensor needs to be wired/run?

You were not getting a CEL before? When boosting?

 

[Captain KRM P5]

no, never. it must be because of the bypassing done to the stock unit

** BEWARE POOR MSPAINT IMAGES **



This is how the stock map sensor was set up with the BEGi FPR;

this is how we have it set up now;

how is it supposed to be best setup?

best picture evAr

HAHAHAH!!

this is what the guy at SPD told me to do
atleast thats the way I understood it

HAHAHAH!!

too dark right now for digicam

Sweet pictures....

Now that I know what I am looking for, I'll take pics, but from the best of my memory, we didn't touch the stock MAP sensor on my car.

You do however have to get the Haltech Map sensor it's own vacuum source. That's probably what is causing your problems.

Is that pressure switch part of the factory setup?

 

[Dexter]

Yeah all that stuff up in the right corner is stock

 

[jrodhotrod]

Pictures are here!

It was as I suspected, we left the factory MAP sensor alone, it was totally un-touched in the installation. I have included pictures of my factory MAP sensor and the MAP sensor used for my Haltech for you.

cool thanks for taking the pics and for the info!

Hello Jared,

I like the new strut bar.

The map sensor does not need to be bypassed with the E6X since the stock ECU is doing nothing to fuel or timing. With the F10X, it needs to be bypassed, so it always read boost and to prevent detonation. We never get a CEL from the stock Map sensor unless we go above 15 PSI of boost. Right Jared?

if the stock MAP sensor is a 1bar sensor, it will go nuts the second it see's boost
SPD told us to bypass the vaccume valve to the stock map, the guy at SPD told me that the vaccume valve prevents the stock map from seing boost
ken has not driven past 4psi yet
Jared has his vaccume valve plugged in, so his stock map sensor will not see any boost

well I will take a picture of how this thing is bypassed and you can tell me what you think. Each time I have driven the car, the third time I go into boost as soon as I hit above zero vacuum, the check engine light goes off. not at 4 psi, not at 16 psi, immediately above zero.

I have never boosted over 7 psi on the T3 since I installed this engine.

Yup, no CEL for me.

these are night pics but right now the best i can with a digicam, 40 degree weather and some flannel pajamas. so sue me.

the white hose tee in the back ground comes from the intake manifold. it tees off (as shown in my previous ms paint pics that are true works of art) to the new MAP sensor on the driver side and to the old MAP sensor on the passenger side.

with the BEGi fmu I never screwed around with the MAP sensor or the so called pressure switch and never got a check engine light under any condition.

 

[Captain KRM P5]

nothing new?

well tomorrow I am going to re-route the MAP sensor the way it was prior to installing the haltech. It never threw a CEL with the fuel pressure regulator and I don't see, all things considered, how adding the Haltech would cause it to do anything different.

i'll keep you all posted.

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.
