Will be work with me megajolt / edis system?

cheers

Absolutely.

The red gains you +20HP- I say this with confidence, as I run the Accel pack, which has bright yellow terminals.

In all seriousness- the aftermarket units often cost less than the generic OEM replacements.

In fact, almost any coil pack will work with the EDIS system, which is nice as some coil pack packaging / mounting styles are better suited for a particular engine installation/layout.

I use the ACCEL also(Jeg's), it works absolutely fine.

Ive been reading this forum for 3 days now... a lot to digest. I just found out about this product this weekend. I have a sunbeam alpine with a ford cologne 2.8 v6 conversion. I wanted to upgrade my ignition, so i bought a mallory box, it arrived doa. they sent me another one, it lasted a week. Now im just usiing a ballast resistor, coil, and dizzy. It falls on its face around 5000 rpm. After reading all this, i went to a upullit yard today, and got an edis 6 and sensor out of a 4.0 explorer, which has an L shaped configuration and also a straight sensor out of a taurus. They wated $40 for the coil pack,so for that much i thought i would go aftermarket. Would this one work and does it seem lilke a good candidate or would the accel be a better choice? They are about the same price.

My next question is map vs tpi. Which is better? Right now i have a stock cam, but as soon as a rebuild is needed ill be going to a cam with a lot of overlap, so i think that will mean low vaccuum? Im excited about finding this and cant wait to get everything together and get started on this. Any advice or comments would be appreciated. Thanks in advance. Robbie

If you have a throttle body or carb with a common manifold, I would go MAP sensor. It doesn't really matter how much vacuum you have, just that there is some change that the sensor can show to the Megajolt.

If you have six individual runners, I would go TPS. I did this with Webers on a flat four with four separate throats.

That coilpack looks fine.

Thanks for the reply. I have a holley 4 bbl. As soon as I figure out the trigger wheel arrangement I'll be all over this.

I did wonder which was better.. but as I have a TPS on my carbs already (Kwacka Ninja Carbs as they were cheaper than the "other" options and look WAAAAaaaaaay cooler ), that was the route I went.

[socorob]

Are there any operational/ performance differences between the two or is it a matter of setup/ preference?

[DannyP]

Setup/preference.

4 cyl, not bad to have 4 lines and a vacuum canister, as long as we are talking separate runners/carbs. 6 cyl it gets messy, 8 REAL messy. Common manifold MAP just makes sense, it is easy and accurate for load-based advance.

That is just my opinion, your mileage may vary

i have a holley 4 bbl, and an offenhauser manifold thats common. i have a vaccuum port thats just blocked off doing nothing, and i saw a tpi for a holley 4 bbl. Just trying to figure out which kit would be best to order for my car.
