Well, I fitted the pressure gauge to my FSE this morning.

Ran the engine up and found that the pressure had been set to 60 psi with the vacuum tube disconnected.

I've readjusted it down to 48 psi now and I'll see if that makes a difference to the lumpy running. It already seems to be ticking over better.

Oh, and I put a good shot of carb cleaner into the manifold too...

Lumpy running ??? i thought you had it tuned with the valve on, it can run up to 80 odd psi, so how where you getting lumpy running after tuning ?.

I've no idea Andy. But the engine has definitely been missing at about 2500 rpm when pulling gently in 2nd and 3rd, and it only started after tuning the FSE.

After the tune-up the power and torque curves were well away from the normal smooth Mazda readings so I can only assume that things weren't setup correctly. I've since heard from one or two people that that particular garage doesn't have that good a reputation when it comes to tuning, so I'm steering clear of them from now on...

Ken

Oh, and I had the battery disconnected for about an hour, so that will have cleared any codes too.

Got ya now m8 lots off places up here, that think they can tune a car but couldn't tune a 1 string violin .

Did the place have a rolling road in it ? cause the fse is deff the kinda thing that will benifit from the rolling road tuning.

And did you have to use any PTFE tape to seal yours onto the valve ?.

Andy

 

[kenholland]

Yep, rolling road, 4-post lifts, the works.

Trouble is they're a Vauxhall tuner and, although they do other cars, don't really have a good reputation on them. (Mind you, my Bro owns a Callibra 2.0 and even he won't go there.)

Ended up using my own rolling road to tune her by feel.
Up and down the dual carraigeway this afternoon stopping and tweaking a bit more at the end of each run. I've got her set to 50 psi now and she feels great.

I did as you said Andy and used PTFE on the thread (see, I do listen to you). No leaks anywhere (touches desk)

Cheers for the info,
Ken

Up and down a duel carraigeway LMAO, i could just see you doing that up the road ok lets stop and alter the flow rate,ok lets try that , ok lets stop and alter the flow rate .

Thats musta been a site to behold m8 .

Glad you got it running nice now ken, and nice idea about doing it like that .

you said that you used carb cleaner and i presume u've prayed it in the intake manufilt (not much use spraying it in the exhaust mani, is there)- just be careful with how often u use the carb cleaner cause in the throttle body u've got butterflies and they sometimes have a small o ring seal on the outside diameter of the butterfly and to much carb cleaner damages the rubber o ring and then causes it not to seal of properly.

thought i would warn you.

 

[Mark 626GT]

Does anyone know what the FSE runs at (psi) before adjustment?

Did I see someone say you can get a pressure gauge to adjust them with?

 

[BeDlaM]

Mark

I got the gauge fited to mine now, and Ken, and i turned mine back down to what was nearly where it was at before putting the gauge on and was around 29/30psi m8, but can't be exact, but it won't be far off that, before install off the gauge.

Andy

PS
you can get the gauge from motorsportworld up here, and don't forget to mention the board when you call them, as Mike (Chastiser) got a mail sayin gthey would discount for us .
