Thanks Denis I hear what your saying and it makes sense! Just th guage manafacurer states 'connect to your narrow band sensor' !!!!!????? I have seen wideband kits with a sensor/guage, but would a wideband be compatable with the ECU? also are the wideband sensors '4 wire' ??? Sorry to keep asking q...

Re: Oil pressure

I too suffered with low oil pressure at tickover when hot (around 5-10psi) it picked up well enough with revs, but seemed frighteningly low to me on tick over having been used to a straight six Triumph. I have been told by an "Expert" in Rover V8's that these engines have low pressure high volume s...

Intermotor part number 52730 Thankyou! I forgot about the 10v stuff though! I have some smiths gauges and just got to buy a new water temp and oil pressure- do I run a voltage dropper over all the gauges? The ones I have are classic stag ones I think. If the gauges are hot wire types, they usually ...

I've got some figures by scanning the cap and rotor then drawing them out on the computer. Distributor degrees. Rotor arm contact is 14 degrees wide. From leading edge of rotor arm just lining up with front edge of contact to trailing edge to back edge of contact, 22 degrees. So it looks like 44 deg...

You do have two alignments to achieve- one is making sure the trigger is at the correct angle and the other is ensuring the rotor is where you want it. I set the engine at 28' btdc - which is what I considered to be the "average" advance - then turned the dizzy around until my rotor was aligned in ...

As Ive little experience with MS. I can only assume you can electronically set the TDC position within the software like every other ecu, and that relative TDC position in a mechanical sense isnt fixed rigidly to being in a certain place. Im sure Phil will clarify if its possilbe or not. I'd be ver...

Yes, as I said it does matter where it points, but its easy to swing the dizzy wherever you want so that it works without crossfire issues. Just re-adjust the TDC pickup position within the software after the rotor arm/dizzy is positioned where you want it As I said, it shouldnt be a big deal. Righ...

its no big deal. Just weld up the advance mech. Rotor arm position does of course matter with regards to it needs pointing at the post in the cap. But you can rotate the dizzy anywhere you want to align the rotor arm. Think it is rather important to get the rotor arm/cap phasing right to prevent cr...

Yes it does, thanks for reminding me of it. I was however hoping someone had done the same using my particular dizzy - a Lucas 35 DLM 8.

Locking a distribtor for use with a MegaSquirt

Newbie post here. I have a bog standard 3.5 RV8 EFI in an SD1 EFI, so originally using the Lucas flapper injection. I'm now using a MegaSquirt fuel only with great success. Much more grunt - but still needs fine tuning to get the best economy. I'm going to convert the ignition to the MS too - and al...
