Yeah it's easy on a car that already has the sensors needed in place and calibrated.

Some of us were doing that 15 years ago ....

The lap tops back then must of been suitcase size, and a pretty penny to boot

Forgive me Dave for been silly! but Sandy you remind me of the Fast and the Furious Films

not that you look like Vin Diesel no! but the fact that you were doing this years ago with GNs and laptops when most Fast and the Furious fans were still in Nappy's or should i say Diepers?

It was Sandy demonstrating his laptop to me at the Nats once that got me interested in doing this one day in the first place.

I didn't have time last night but hopefully tonight I can record the idle again after a few changes. I did get just enough time last night to increase the diameter of the advance stop in the MSD distributor by 30 thou. That should get my timing curve about where I want it.

Once I am happy with the way the engine idles I can get on with finishing the car and getting ready for an MOT.

Got a bit of a leak from the converter seal in the front of the trans though. I might have to drop the exhaust and trans and sort it out.

2 steps forward, 1 step back, eh? Looking forward to this being back out on the means streets of Newcastle! Let's hope the convertor snout ain't cracked like my one was once.......Looking ace, Dave, bet you can't wait!!

It's a new TCS torque converter Kev. But it was sitting in the seal for a while (couple of days) before I fitted the box to the engine. I probably warped the seal that way.

I will probably ignore it for now until after the car is on the road if it is not too bad. It takes weeks or months to get a 1 meter long wet patch under the car so it can't be that bad a leak.

Didn't get everything I wanted done last night due to a massive water leak from the thermostat housing. :s008:

I removed the thermostat to drill some holes in it but when I removed it I found that I had already done this and had forgotten. :disbelief:

After re-fitting it and firing up the engine the seal was leaking like mad. So I had to pack in for the night. It was getting late anyhow.

What I DID get done though was check the vacuum level with a mechanical gauge. It turns out the MAP sensor is reading perfectly. I really do have a fraction over 9 inches of vacuum at idle. That is about twice the vacuum I had with the old hydraulic camshaft.

I also blocked off some of the holes I had previously drilled in the carb throttle blades to get the idle right with the old cam. That seems to have worked well too.

In case you are wondering how you fill holes in throttle blades? I take a tiny bit of brazing rod, drill the hole to the same diameter, and counter sink each side slightly.
Then, with the bit of rod in the hole, I Bananarama! in a vice to expand the brass rod and form a rivet. After filing flush I also stake the center of the rivet on each side with a center punch.

Good tech tips there Dave, with that much vacuum you may even be lucky enough to have some brakes!

I hope you don't think I would go back to a wimps power brakes Ivor?

Good man!

We don't want any of that shirt lifter power brakes nonsense around here!
