Timing issue Nodiz MJolt
Turbo Mini Forums

Ok guys run my engine for the 1st time since rebuild yesterday, after i managed to get it going i put on a timing light and with the engine running No1 is firing on 0TDC is this correct. Surely no engine runs at 0TDC, should i go for what the Haynes manual staes for a standard MG turbo..I should mention that i am using a trigger wheel setup with Nodiz, Can anyone advise..

Also the Float chamber vent should i permenatly block this off,
Does anyone have any ideas for an exhaust just have the Maniflo down pipe at the Mo..

Have you put a map on your nodiz?

If something is worth doing, it's worth doing half of.

did you set the engine at tdc when you fitted the trigger wheel and cut 90 degrees tooth out?

if you have done this i wouldnt worry to much about timing as the rest advance/retard will be driven by the software i think.

the nodiz does have some spunky things to try and help you set TDC but i would check your map to see what that says

Hi thanks for your replies it has a pre installed map from nodiz, I you can advance and retard the timing using the butons on the unit, but should I not have it set to -BTC as surely the cylinder will fire to late, just wonder has anyone put on a strobe on there mapable ignition to see what they are running on tick over....thanks

how did you install the trigger wheel?

when i did mine on my MJ the MJ gave me the exact reading as per the timing gun.

can you answer some of the questions

- how did you install the trigger wheel (you should have had the engine at TDC then cut 90 deg of the pick up)

- what is the software saying.

do you have fixed firing selected in the software? of so this puts the spark on plugs 1&4 at what the ecu thinks is 0deg for setting up

Thanks for the interest guys, I couldn't see this facility in the soft where. The instruction said to get it to fire at 0tdc, its just strange, shouldnt it be around the 7BTDC at 1500 rpm..

Also have you gjys blocked off your float chamber vent.. cheers again

On the Nodiz, enter the fixed firing option so the green light flashes 5 times. This will set the Nodiz to fire at what it thinks is 0BTDC. I kept the original timing pin marks on the timing cover. Use a timing light to check it is firing at 0BTDC. If it is not, use the two buttons to advance/retard the timing. Once sorted, turn off the ignition and it will store this. Upload your map and your sorted.

The 7BTDC you mention abouve should be on your ignition map. The 0BTDC feature is just to double check the Nodiz is firing when it should be.

Hi James

As the software doesnt have an offline feature (pain in the ass) are you referring to buttons on the Nodiz or within the software?

Sounds like an un necessary complication pushing buttons watching flashing lights and powering down. Thats the kind of thing you had to do back in the early 90's when few had access to laptop computers. These days you can do that sort of thing with you phone.

I am now less impressed with the Nodiz. Just my opinion

Might be better to ask on the nodiz site as there is very little experience of nodiz on here.

Will everyone stop saying 'NoDiz' its making me feel sick.

It is such a shit name!

Indeed the NODIZ will fire at 0* if you set it onto setup mode, and yes, like the 90s when you could easily adjust things WITHOUT a laptop, that is why that mode (and indeed buttons) are there. It costs MORE to add the buttons, and MORE time to add the firmware for adjustments without a laptop, it is a help, not a hindrance....

You can use a PC if you wish, but some people don't have access or the know how.

If your trigger wheel is out, then it will fire at what the map is telling it to (approx 10* at idle), so I am guessing your trigger wheel is out by approx 10*. Use the buttons, a couple of presses, and this error is automatically accounted for from then on.. try doing that with EDIS

As for the name: NoDiz... No Distributor... I thought it quite catchy :)

Could of gone all american I suppose... Super Power Squirting Street Rod Power Chip, but meh...
