I think it starts better but I'm comparing it to the winter - it's hot here at the moment I don't really know what I'm looking for regarding timing - unless it misfires how can I tell if I've got the right setting or not? The table I had loaded used the distributor centrifugal settings from the manu...

Ventured out onto the open highway today. MAP readings are still very noisy, despite having a mig tip and a filter inline (although the filter is quite coarse - it's not a paper one). However, you can just about see that the load readings go up with RPM on the road so that's OK. I've tried filtering...

I also connected a timing gun and ran the engine on EDIS alone. It said my timing was 15 degrees so I corrected that in the software. However, I noticed that the timing gun was saying about 40 degrees when the laptop was showing me 18-20... perhaps it's a crappy timing gun because the engine is sta...

I'll see if I can log some road data tomorrow as realised due to the bank holiday I won't be able to buy a fuel filter

You might be right, Chris, let's hope so. Bit nervous about taking her for a drive as engine bits not easy to access once seats are back in (it's a forward control vehicle) but hopefully putting the distributor back in should be a relativly easy side-of-the-road job once you can see it

OK, after fabricating and installing a new starter mount, I set about wiring this thing in a bit better. It's still not perfect and the HT leads are a bit tight, but she runs (and seeing as I installed a relay... stops again too!) As suggested by Chris, I pushed a mig welding tip into the hose to ac...

For those of you who don't know what the vehicle looks like:

Hoping to get the wiring tidied up a bit soon



At least it all works (although starter motor fell off so can't do any more testing at the moment!!)

I'm guessing logging data whilst you're driving along won't be too easy... unless you've got a REALLY long extension cord!

Have you tried just changing the setting up and down to see if it makes a difference? What figure did you settle on, if so?

Thanks, Chris. I've got to spend today fabricating a new starter motor mount as the old one has perished (yes, for some unknown reason they hang a huge 24V starter motor off a rubber mount) but once I get it running again I'll try that

Yes, I'll try putting a fuel filter and/or Mig tip in the line to see what a difference that makes

This was a static test. To tweak the throttle you have to stand directly in line with the fanbelt. Considering I've had problems with the nuts falling off, it's not a very comfortable feeling! Once I get it wired up properly I'll take it for a spin & see if anything differs

I've tee'd into the brake servo feed. Between the T and the servo there is a non-return valve. I've temporarily disconnected the servo and turned the valve around to block it off I'm using a 2m length of silicone vacuum hose which I would have thought was flexible enough to damp the readings Starter...

I've just logged a short run of my engine but am very confused about the kPa readings. As expected, when the engine is not running, I get a value of around 100kPa (I've trimmed the zero rpm values from the attached graph). The values then sit at roughly 70kPa but DROP as the rpm increases - this is ...
