Viento Back on the road.. now Megajolted
Well having missed the heatwave of the summer because my Opus dizzy gave up, the car finally got back on the road yesterday. I managed to take it out
for my first really long drive, 3 hours and 75 miles later I don't think i could have possibly been more relaxed, and all for the bargain price
of about 17 quids worth of fuel (oh and the price of the megajolt setup but wasn't thinking about that!). I'm not sure there are many things
that can compete with that for so much entertainment for so little money.
The car still needs a lot of dialing in; carb idle, accelerator pump, advance map, suspension and tracking etc but first impressions of the megajolt
are pretty impressive, the opus system was so bad I had to really be careful with the accelerator not to make it misfire through the carb when putting
my foot down. The edis and megajolt set up seems to work fairly well even on the default map, and all nastiness has gone away, there is still a little
hesitation in a few places but I think that should tune out with time.
Installation wasn't too difficult just time consuming really, the worst bit was working out how on earth to mount the coils because each one
feeds both cylinder banks. Eventually made up some brackets and mounted one at the front of each cylinder-head; there probably would have been more
space at the back of the engine but having seen how flipping far a spark can jump I decided it was probably best to get them and the HT leads as far
away as possible from the carb and fuel hoses!!
On the whole I'm pretty impressed with the whole system, 380 quid (inc vat and delivery) was a little painful, but it probably would've cost
100 just to get another dizzy just to get it back on the road and now I have a map to play with too, and have the hard rev limiter to fit at a later
date.
I got the whole setup from trigger wheels, not their full V8 kit because I couldn't see how I could be certain that all of their brackets would
fit my setup properly, I gave them a little bit of stick about their postage but they seem like a genuine company and I deffo can't fault the kit
or service I recieved - they even put a few sweets in the packaging!  Would def recommend them to anyone that wanted an MJ system.
Few piccies:

I made it and designed it based on the Dax style (which is actually pretty good for getting the primary lengths close) and some online calculators for
the primary lengths.
Deffo glad to be a road going beaver again!

Glad to hear your happy with the megajolt. I switched over to it last year and am very impressed compared to the dizzy.
Yours looks a neater installation than mine-
I use the rev controlled outputs to switch a series of leds on my steering column to act as a shift light.
If you develop a good map then I would always like a copy
My map is just guess work but runs well.

what carb are you running
your filter is way to restrictive.
I now have a 3 inch 14ch diameter filter.
anything smaller results in a starved engine...

Haha possibly not, i left out a couple of photos due to shame
I think I'm going to do something similar because my RPM counter is digital and its just too hard to read with a quick glance whilst trying to
keep eyes on the road.

Its a weber 500, I used to have an edelbrock pro-flow foam filter on there but Paul at V8tuner.co.uk mentioned he'd heard of at least one bonnet
catching fire becase of them kicking out petrol fumes into the GRP. Do you reckon that filter is too small then? I wonder if that is part of the
hesitation, I'll give it a try with the old filter for a few miles and see how it feels. Thanks!

I didn't want to jump in, but if you look at pics of similar installations on other websites you'll see that the filters are far larger in
diameter than yours. Might be nowt, but it might contribute to poor running at higher revs/engine loads when the throttle is wide open.
