NO BOOST on MK1 Turbo

[jay140285]

As you know I have had an eventful and busy week

Crank Seal now sorted

Timing Sorted

Tappets now nice and quiet

BUT.......................................

I have got no BOOST, its driving like an N\A car, makes all the right sounds but just go turbo power.

Power delivery is smooth, but just lacking on the Turbo side now.

What up now????

Does it go when you put your foot down or does it lose power altogether?

[jay140285]

Doesn't loose power, feels like its only 115bhp again. it just feels like its driving without the turbo.

Popped a boost pipe off?

[skinny]

when you say timing do you mean on the cas or the cambelt?

[jay140285]

Cam Belt,

TDC and then the top cogs as they should be.

[jay140285]

Just found out that because I have a link ECU, the timing needs to be set up using that.

Only problem is that Mark who did the setting up is on holiday!!!!!!!!!!!

Arrrrrrrr and I need the car.

The timing on the Link shouldn't need to be touched - it should have been set up with stock timing i.e. 10BTDC. All you have to do is make sure the timing is set to 10BTDC and the link will do the rest. Worst case scenario is that the link was tuned with the timing at 14BTDC in which case you'll lose 4 degrees of timing which will lose a little power but will be perfectly safe.

As for the lost boost - make sure all your vacuum/boost pipes are fitted properly and aren't pinched/kinked.

Errrr followed Miata timing set up on youtube "MX-5 Miata Timing Belt 2 of 2 Mike's Place" and set it up at TDC not 10BTDC

Yes, that's cam timing. The timing I'm talking about (which is what the FM Link will be controlling) is the ignition timing which is 10BTDC as stock

[jay140285]

Oh ok,

That's what Mark is talking about that is controlled by my link ecu.


I am going to have a go at reading the instruction, if not wait for Mark to get back of his hols.

As long as you set the base timing to 10BTDC it should be fine to drive as it is. The Link shouldn't need are tuning at all.
