it dies? or what do you mean? did you check ignition curve with a strobe light? Idle setting at carburator and synchronization confirmed?

In my current EFI config, I am running 10-11° advance (@ idle, 900). There is lots of debate whether this may be too less for a 143 HP PI Engine. For my 170 HP and CR 9,5 it has suited me. The curve I presented with my previous 123 config, is indeed higher. about 15° @ Idle 900. This seems to be the value for best torque in lower RPM....and yes, it includes static advance. These are the numbers you see using a strobe light. with a max. 30-32° depending on CR and engine config. If you do not have a rolling road, I mentioned following test: put in 3rd. Start at 1.500 rpm, pull upto to 4.000 or 4.500. use stopwatch. Repeat. Increase curve with 2 degrees increments. When indeed pinging occurs, back off 2 degrees in higher RPM range. Jochem

Hello Albert, on my previous setup which was with 123Tune and carburators, I did not use MAP. Just the curve as I mentioned... Jochem

what kind of ignition do you have? You probably have about 10 degrees advance....try to reduce towards retard......modern cars even go down to -10. Jochem

Do you have valve stem seals installed? Jochem

Hello Matt from Eyam, not sure what ideas you are looking for? Ideas on what to do with the engine?? Jochem

sorry guys, I will use the metric system: new/overhauled engine: 0ml - 500ml @ 1.000km used/normal engine: 500ml - 1000ml @ 1.000km (noted in brown bible) Anything more than 1000ml @ 1.000km should be checked. Causes will vary from worn pistonrings to valveguides etc. etc. A pressure los test can give you a hint on the cause. Jochem

I thought the adapterplate is there to fit the MX5 Gearbox to the TR4/6 engine? Or did I miss something? Jochem

...not sure....does not seem steel with yellow finish..

will do !!

Hello, Item 94. What material should Gear (96) be? This is the gear into the camshaft. I have a carburator shaft which has a steel gear , and a PI shaft which seems to be out of brass (?). The PI driveshaft has a mounted bearing, any play or measurements I need to consider? Brown Bible only refers to end-float using paper gaskets. (109).

I cannot login on that particular member page....but Conrad may reach out to me....

I am looking for a metering unit with pedestal...preferably CP. Does not need to be fully reconditioned, but in decent condition. Neil offers this one: https://www.ebay.co.uk/itm/TR5-6-LUCAS-TRIUMPH-METERING-UNIT-AND-2-5-PI-on-EXCHANGE/143621482443?hash=item217081e7cb:g:EfwAAMXQ5fVQ8TXa but since the price is on an exchange basis, I cannot bid on it.
