Sunday I did my first long drive with the megajolt, 200+ km without any problem! just loving the megajolt!!

Also made a new "extra" dash for 2 gauges and some switches

sorry for the blurry pics but they are taken with my cellphone

a quick question for the technical guys, megajolt is now also controlling mine electric fuel pump, but when the engine is cold the idle is around 630 rpm , but sometimes it goes below 600 and then cuts of the fuel pump because the trigger is set to 500 with a hysteresis of 100. 500 is now the lowest i can go with the software, is there a solution to drop the trigger-point to 400?

Can't help you there. Might be the penalty for using a DCD carb. It doesn't have a fast idle setup like a DGV, just mixture enrichment doesn't it? What idle rpm do you use when the engine is on operating temperature?

It's idle is around 650 when on normal operating temp, when he's really hot it's a bit higher

That is low. What does the Ford manual say? Idle specified by Saab for the same engine is 800-900rpm. Aim for 850, it may solve your problem.

Just out of interest, how does the map look you are driving with now?

That isn't even the lowest i can go

I have set the idle up like this because it is the lowest rpm without losing oil pressure.
I just like the sound of the V4 when idling that low and the engine has no prob's with it

Here is my latest map, but i don't pull it trough till 6500 rpm like the map I've got from you.
For me it's the best map i have driven yet, with a lot off power en very good response on the throttle.

A map going to 6500 isn't mine. With standard cam and no reinforced valvetrain 6500rpm is not safe. My latest map goes to 5500. For the setup I run now that is more than enough.

ow sorry my mistake, I've saved another map with the same name...

I now pull trough until 5700 rpm when the hard rev limiter cuts in. my shift light goes on at 4900

Have you already implemented a temp sensor? any advantage's? I'm thinking of using a lambda sensor to the aux input.

No offence taken

. I haven't come to connecting the temp sensor yet. But now that I also have Jolted up my Saab 96 I will try it there first. I want to use the existing temp sensor and as much of the original wiring harness as possible. The plan is to hook it up to the lead between the gauge in the dashboard and the sensor and separate both circuits with diodes. A diode could reduce current, resulting in a faulty reading on the dashboard gauge. I will give this a try first and when it works use the same method on the Sonett. The clockwork on a 96 is much more accessible than on a Sonett, so it is easier to try there.

Keep me posted on it!!

Today made up a dummy distributor, so i could elemenate the stock dizzy!
I'm convinced that the megajolt system will not lett me down!

Also made some brackets to hold the ignition leads so they aren't drifting around in the engine room any more

Pictures coming soon!

As the main reason for me to start with Megajolt was to get rid of the dizzy I am very interested in how you did your dummy dizzy. Haven't come yet to sawing an old dizzy in two and adapt it. Will be the next project after refurbishing the front wheels and making a new vacuum point in the inlet manifold of the 96.

As promised, some pictures!

Here is my dummy against the old stock dizzy

And here some close up's

The dizzy also has the function of turning the oil pump around, this is why i needed to keep the lower part of the dizzy with the sprocket and connecting rod.

But when you cut the dizzy in half you get alignment problems because there is no bushing, this is normally located at the top of the dizzy. So i took that out as well and on the lathe i machined these 2 together with a press fitting. And at the end of the shaft i made a cir-clip to avoid that the shaft falls out of the holder.

Then i needed to do something about those ignition leads!

I like things to be neatly in the engine room, and the ignition leads were not!
So i made up some brackets to hold them!

I really like the look of it now with the dizzy out and the ignition leads nicely in place above the rocker covers!!
