VW MK1 16V
Hi to everyone,ive got a vw mk1 golf with a tuned 16v vw engine runing twin carbs,at the moment i'm using the 16v loom,ECU,TCI,COIL and DISTRIBUTOR,i keep on having problems with this set up,can i use Megajolt,if so what system,and parts do i need,and how easy is it to install.Thankyou for your time

...im doing this to..!
I am running a Mk1 Golf with a 16v KR engine. It has twin 40 DCOEs fitted and I am currently running the standard VW engine management....
however...
I have built a Megajolt Lite board and am in the process of making a loom to link it all together.The board build is quite straight forward. All the parts can be sourced from Farnell-in-one (on-line). The most difficult thing has been making a crank sensor wheel. I raided the local scrappy and found a 36(-1) timing wheel and pulley off a Ford Siera, I also raided the other Fords there for all the EDIS parts needed. I cut the pulley out of the timing wheel, if you do this be careful as obviously you dont want to damage the timing wheel!
My current idea to mount the timing wheel to the engine is to use modify a VW 16v PAS Crank pulley (this is a pressed steel part that bolts directly to the existing crank pulley). I am having a chap at work turn the VW pulley down so the Siera toothed wheel can be fitted to it. Then you just need to mount the sensor, I have modified a VW PAS pump tensioner bracket to hold this. 16v Golfs are quite rare to find with PAS, however you can grab the parts off Passat 8 & 16V's and also some Seats.
I shall be using the MAP sensor to measure engine load.. but as I am running twin DCOE's, as you are, you will need to tap your manifold to create a balanced intake pressure pipe to correctly sense manifold pressure, this can be done is a similar position as you will have for your brake servo vaccuum pipe... I dont know what the implications are for using only one inlet tract instead of all four? maybe someone can help us out with that?
Finding the standard timing map is quite easy, either do a search on the club gti forum or on vwvortex forum.
Let me know how you get on...

Thanks for your reply,will
Thanks for your reply,will let you know how i get on.
Alright Johnathan!i know of
Alright Johnathan!i know of a complete system but it uses TPS instead of the MAP sensor,will this work.CHEERS

yes i think it will work....
Yes I think it will work, however in my opinion using the air pressure (MAP sensor) is better as it is amore accurate measure of the engine load.
