Greddyturbo1

Questions about Greddy Turbo.

1.Instructions say to hookup a vac. line from the internal wastegate to either of the intake manifold plugs.. I guess it doesn't matter which one, But I wonder if we hookup both intakes with a T and then hookup to the wastegate, Maybe it would give us a more reliable vacuum for the wastegate. What do you guys think.

2. The Greddy kit also states to hookup the pressue sensor to the intake just behind the throttle body.. But the Profec-EO1 states that to make sure you install the pressure sensor pointed down. Does anyone know why, and then shouldn't the Greddy sensor also be pointed down for the same reason...

I don't know about #1, I just picked one.

And I believe your correct about #2.
I looked up the instructions to the EO1 and it's the same pressure sensor. I have mine zip tied sideways. I'll adjust it to have the vac hose pointing down tommorrow.
I do not know why they need it to be pointing downwards, some kind of zero calibration or something.

i have installed my turbo and am still having some pronounced issues.

1. greddy sent me thier latest map about 10 days ago. still backfires and need to get jeff's map installed. this one backfires like a mother

2. stalling when shifting to neutral after cruising at same speed or accelerating

3. smells very very rich

4. pronounced uneveness (jerky) between boost and vacume and sometines just when driving at steady speed (usually in 5th at 70-80)

things i have done:

a. connected the top bov to a T fitting...one branch to downward facing tube just behind throttle body and the other branch to the supplied greddy sensor that plugs into the e mangage box.

b. disconnected the dongle. black from harness to black on other dongle in all japanese writing. connected the green and white wires together. left the pink and white free

c. adjusted the bov

I am wondering now after others concerns about whether my hi flow cat and midpipe from SR is interfering with a smooth running system?

what else can i check do or modify to find the key to this problem?


also, what is the best power lead for connecting the greddy control unit II (for bf gauges)

The hiflow cat/midpipe may be an issue. The emanage map isn't tuned for that. Boosted posted here about his car not running right with his midpipe on, but lost some boost once he went back to the stock cat.

As far as the power lead, I tapped into the cigarette lighter positve lead for my guage and boost controller.

rudy8

yes

i changed out my SR hi flow cat and midpipe and re installed the original cat and midpipe.
greatly improved driveability...i would go so far as to say it is totally not compatable with the
SR. thanks for your help adrian...all your pm;s helped alot!

Can someone take a pic of this?

The air fuel mixing hose connects to a fitting on the air filter.

adrian-1

I'll post the picture tonight. It's on my home pc.

Speedrx8er

Adrian thanks.. Your post clear up alot of the confusion I had when I was reading the
install instruction.

adrian-1

here's the pics of the intake with the hose connecting to it.

Speedrx8er

Thank Adrian. I see that you remove the small metal tubing that was on the airbox tray.
Or did you re-route it?

adrian-1

I removed the metal line along with the rest of the vfad stuff (all the tubing in the front bumper area).

Speedrx8er

Thank Adrian,:

Other question. How the heck did you get the PCM cover on after you hook up the e-management?

adrian-1

I chopped up the cover using a dremmel. Trimmed some of the side facing the cabin. Plus removed the bracket that the pcm was being held in. I'll check for pics of it tonight once I'm home.

link for the full instructions does not work

You can find the instructions on Mazdamaniacs site

Please Varify:

The stock oil Pum air hose has a Yellow line at the end.
and the stock Jet Fuel Mixing has a White line at the end..
thank

adrian-1

I didn't have my digital camera with me, heres a couple with my cellphone. I need to cover up the wiring with some electrical tape or something just so water and dirt doesn't get in.

adrian-1

That's correct.
So the yellow line hose goes to the S-1 suction pipe and the white line hose goes to the airnix adaptor.
The other nipple on the S-1 pipe is for the oil filler pipe hose.

Speedrx8er

Adrian: Thanks for everything.
I don't know if you had to get a new O2 or not. But you won't happen to know where
the other end hook up to?

I'll start her up tomorrow. Once I put in the new O2

Speedrx8er

Does it matter which nipple I put it in? I put the Oil filler pipe hose on the nipple closet to the Airnix

adrian-1

My O2 sensor didn't break. Lucky, I guess. Not sure where it connects. Can't you just follow it up? I'll see if I can find it in the manual.

Doesn't matter which nipple.
Also, I believe it'll still run if you switched the metering pump hose and airjet hose.... they're both incoming air, just one isn't as turbulent.

Speedrx8er

Thanks.

Yes I tried to follow the wire. But it was wrapped over the transmission.

hate to jump in but i have a question, i installed MazdaManiac new map (i think anyway) and i took it out for a run and 3rd gear with WOT the air fuel was at 13. is this good i also noticed that b4 and after when at a light or stopped in idle the guage reads 15.5-16. the egt reads between 5-7 and even if i am just crusing it goes that high..

You might be lean. It depends on where you are in the RPM band when it goes that lean.
Also depends on how you are measuring your A/F.

Did you reset your PCM after you installed the new MAP?

youngpit

no i did not reset the pcm i did not know i had to oooopppssss. thats i will do that when i check to see if i installed the map correctly. ( this is why i pay ppl to do this whole tuning thing)
