My draw through turbo

No problems.
Well I've changed all the leads but here's an update Von the random misfire. Now when I get the misfire the rpm gauge also starts jumping aroubd, now the rpm gauge gets its signal from the negative side of the coil so I'm thinking is something earthing the coil causing the rpm gauge to jump around and the plug/ plugs to miss?

Disconnect the tach wire from the coil. Then try the motor again. If the misfire disappears it's the tach wire grounding on something. Check the wire for rubbing against sharp edges. My motor used to die on left hand turns. Lol

It is, it supprises me everytime!

[advinnie]

Rpm gauge disconnected and boy do I have a hang over from hell

[rubenski]

Hahahahahahahaaaaa

[madmike]

Haha I don't miss hangovers one bit I quit 20yrs ago

[advinnie]

Well the hangover is sorted, I fixed it by drinking now .
Wow you must be mega old then

[kangaboy]

Wow you must be mega old then

HA!! Have another one there, advinnie

[advinnie]

I will

[madmike]

who me? I'm only 64

[advinnie]

Ha ha ha
Well I made it, 874 miles in a 46 year old bug with a bloody turbo bolted on it

Right found my fault but not to Shaw what's going on.
First of the launch control kicking in was due to me I left it turned on and forgot to remove the wire and it was earthing and cause the launch control to kick in
Any way back to my ignition problem, what is happening is that when I have the laptop connected and the engine at a steady rpm (let's say 2000 rpm) the software on the laptop is show a massive fluctuation in rpm anything from 1500 rpm to 4000rpm and cause of the fluctuation in rpm the ignition system is also advancing and retarding the time. So at 2000rpm my timing should be 20 degrees BTDC but cause the ignition unit is reading fluctuations up to 4000rpm the timing could be anything from 20 degrees to 38 degrees BTDC. Now at the same time my rpm gauge is also fluctuating, but my rpm gauge gets its signal from the negative side of the coil, the ignition unit is what's controlling the coil, and the ignition unit is getting is rpm/timing signal from the points in the distributor. I've now changed the distributor, the points, leads and coil but the fault is still there. Some times the fluctuations are so small you don't notice it but they are there and some times the rpm fluctuations are so great it advances the timing by up to 18 degrees to far for the correct engine rpm and almost stalls the engine and when at crusing speeds the fluctuations in timing cause by the ignition unit incorrect rpm signal cause the car to accelerate and brake when the throttle is held steady.
And other idea on why the laptop/ignition system is getting or showing fluctuating rpms?
Hope this makes sense

[rubenski]

I'd say bad connections?

[advinnie]

That's what I thought but the only input/ signal the ignition unit gets is from the points and I've changed them

[madmike]

CB's black box? what do they say? I gave up on the fancy MSD boxes and simply lock the dizzy @24* single points and a blue coil ,,
only issue I've had since the swap(2 years) was my points wore closed ,,and it still ran just not to responsive to the throttle
