Megajolt advice
pjavon - 22/7/07 at 04:35 PM

Hi All, I'm after a bit of advice, i built my car about 3.5 years ago now so it has twin 45 weber carbs and alpha 3D ignition (2.0L Zetec 1993) which i have since fitted piper 285 cams and a flowed head but when set up on a rolling road it only reached 124.2bhp at the back wheels (149.7bhp at the flywheel) and 130lbs/ft torque @3765 rpm, which at first i was disappointed with until i drove it on the track and although i'd hoped for more power the engine was very smooth and the power delivery exellent in my limited experiance. But now i've been advised to change my alpha system for a megajolt as my local garage is setting up the same spec engine cars as mine and is achieving between 150-160 bhp at the back wheel as they can now adjust the mapping as well (this is not the same garage that set my car up originally).
Obviously this sounds great but i don't want to ruin my well setup engine for some peaky screamer that may make 160bhp at 7300rpm but only 50bhp at 3500rpm so any advice as to weather it's true, or your experiance's with megajolt would be really appreciated as although i built my car i just really bolted this on and got it setup, and if there is another 20 odd bhp to be got i want it
Thanks Paul
P.S. I'm being told £275 for the complete system including shift lights- how does this price compare?

Why not get your alpha ignition mapped? Depending on the ECU you may be restricted to where you can take it as they may have to take the chip out to program it.

What does the £275 for the megajolt include?

The £275 was everything i needed to change over from my alpha to megajolt so basically the unit i supose. Wasn't to keen at the time when he was telling me but now i've thought about it , i'm trying to get as much info as i can. The main reason i wasn't going to get my alpha remapped was because aldon auto are my nearest and there 130 mile away and then if i change anything else in the future i'd have to go back there instead of a garage only 18 mile away who are set up for megajolt.

If £275 is just for the megajolt unit then buy one off someone on here. There are a couple of people making them and it'll cost you a lot less than £275 - ebay prices are ~£100. (you could make it yourself but i'm guessing your not keen on that idea)

£275 sounds very dear. I hope that price includes fitting and setup.

If so then maybe it's not so bad!!

The alpha could be remapped but if you are planning future upgrades then the Megajolt is a reasonable solution.

I had no problems with mine.
