More Ttv Problems

[JeffR 51]

With the engine out while doing some maintenance on my Mi16 I thought it would be a good opportunity to fit my TTV flywheel since getting the correct bolts for the pressure plate.

After getting it back in and everything re-connected, it won't fire up.

I hooked up the ecu diagnostics (Motec) and it's giving a syncing error- ie: the ecu isn't seeing the crank position sensor. I also tried my spare (both genuine) CPS. Still no start.

 

It's giving me a sinking feeling!

Has anyone else had issues with these flywheels?

 

Thanks

Only with the dowel hole not being correct. Never had a sync issue. I'm not sure if there is an air gap sensitivity setting on MoTeC, but if there is, some adjustment may solve it.

What's the gap distance? Is it close to the standard setup? I solved my TDC sensor issues by doing this.

[JeffR 51]

Thanks Sandy for the air gap suggestion. I haven't as yet found where that setting is in the software and am waiting to hear back from my tuner.

 

Peter, I'm using the standard Pug CPS so whatever that airgap is. Even swapped over to my spare but also won't start. As it's the only change I've made and the ecu gives a sync error, there must be a difference between the factory flywheel & the TTV one.

odd that Motec gives issue but not the magnetti ecu's.

My mapper has known issues with this, Not on Pug's thou but the theory is the same, Cannot be anymore help thou

[JeffR 51]

My tuner gave me some homework to do tomorrow & report back!

 

Does anyone know what the airgap is with a standard cps & std 60-2 flywheel?

[petert 586]

A figure of 2mm comes to mind but I can't be sure without checking. Let me know if you need some accurate measurements.

[JeffR 51]

I've just done my homework & the ecu can't see the cranking rpm, and CPs air gap is 1.75mm. Engine tuner says 1.5mm max for Motec. Other issue may be the material the TTV one is made from-maybe less iron in its composition?

 

Peter, where did you get your adjustable one?

Jeff, what about filing the fixing face off the cps until you've taken too much off, then using a fibre washer to space it back out ?

 

I've got a TTV flywheel and Cps at hand if you need any electrical measurements

[petert 586]

It came from Haltech and I made the adaptor to mount it. It's a 12V hall effect sensor however, not a low voltage motronic trigger. The main benefit being shielding isn't as critical and the signal doesn't get knocked around by other stray high voltages. Your ECU needs to be able take a 60-2 Hall Effect trigger.

Erm! I'm feeling quite embarrassed!

 

The crank position sensor & cam position sensors have male & female connectors respectively in close proximity & I made the mistake of connecting one to the other instead of the loom. Once I realised the problem & reconnected properly, she fired up straight away. Phew!

 

Now all that leaves is to drain the fuel tank & send it away for more leaks to be plugged!

 

Thanks everyone for your input, crisis averted!

Eeee Awwwwww! Lol

[welshpug 1,657]

not as bad as Hexamstu plugging the crank sensor plug to the radiator fan thermoswitch

He who never f***s up never does anything!

 

Glad it was an easy fix!

[JeffR 51]

I was quite impressed when I had the new engine loom made up last year & saw that he'd put a male & female connector on each of the 2 sensors thinking that'll stop any possibility of connecting them up wrongly! But I didn't see the obvious that they could be connected together!

 

Luckily my tuner has a great sense of humour when I told him.

Jeff, can you let me know how the car is with the TTV please?

[JeffR 51]

Jeff, can you let me know how the car is with the TTV please?

I won't know until the first event in 2015 which is Feb 14.
