i have heard a lot about the msd ignition. i was considering getting one for my 2003 ford ranger with a 3.0 liter v6, and a 5 speed. would this do anything for me? which one should i get, because i know there is a variety of them? will it help hp and mpg. i need both, but mostly mpg.

another question. in the jegs catalog there is a ford powertech module by Jet performance products. it has one for the 3.0 ranger and it says it will add 30 horsepower. does this really work or would it be better to get the diablo from motorhaven.com? will this module by jet also benefit mpg?

 

IMO, Ford's EDIS ignition is more than robust enough for your 3.0L. As long as you use quality spark plugs, gapped propperly, and quality plug wires, there is no need to consider upgrading the ignition system.

Regarding your chip question, read here:

Are you considering any other mods first? Exhaust maybe?

 

You will be throwing your money away on any aftermarket ignition system!! There will be no performance improvement over Ford's EDIS.

 

Agreed. The MSD DIS-4 will only be beneficial for forced induction or other higher-compression situations. It is no more efficient on a stock engine than the EDIS system is.

 

Or you could always do like me and rip the stock computer and ignition system out and replace it with a MSD ignition and a homebuilt Megasquirt injection computer. Im just getting started with this process so bear with me but I hope to have it completed in the near future. I'm looking for complete adjustability from the system. Am really tired of my engine running lean due to the crappy fuel injection system. Many people say just to chip the stock computer but that may be difficult because the 3.0 is in my '90 ford aerostar. Oh well, it isnt going to cost much more than a chip does anyway.

 

Why do you think you can improve the efficiency of the stock PCM? More fuel is not the answer!!

 

My engine is mostly stock other than free flowing exhaust and a ram air intake and the stock ecu and injectors arent up the task of feeding the engine the proper amount of fuel. When i get on the throttle at all the ratio goes way lean and I get a cel. This injection system may be fine for a completely stock engine but if you do any mods it sucks. Im planning on redoing the exhaust completely and stuffing an eaton m90 supercharger under the hood eventually but need to get the electronic situation resolved first.

 

You have some other problem if you are getting a CEL!!

If your 3.0L Aerostar isn't fast enough for you, it will be a lot cheaper, more reliable, and a lot safer to buy something that is already designed and built to be fast enough for you, instead of pouring tons of money into mods like a supercharger!!

 

The check engine light indicates that it is running lean. I have the proper amt of fuel pressure and all sensors are in order so I believe that the small injectors arent up to the task. So, I'd put larger injectors in but the computer would have to be reprogrammed for them. Instead of that im just gonna replace it with something a little more up to date. I think that a megasquirt with my laptop hooked up would do fine. Oh yeah, im sure that it would be easier and make more sense to buy a sportscar. But where would be the fun in that? In my aerostar not only can i stomp most rice rockets off the line and up to 85mph, I can have 6 witnesses with me to confirm that. When I get my injection situation under control and my exhaust and supercharger in order I should have no problem doing that. Half the fun is knowing that will have something that isnt too common, an aerostar that will haul butt. You wouldnt imagine the satisfaction when you are at a light next to some civic and they rev the engine toward you and you take off and are like 3-4 car lengths ahead of them. The look on their face is enough to make me want to pony up my van.

 

Son, you have a lot to learn, start by checking out these URLs, and see if it's worth the risk of your life, or somebody else's:

First of all, where did I mention street racing? Or breaking any laws for that matter? It is not illegal or unsafe to do a high speed launch from a stoplight. Im not looking for speed, im looking for quickness. Like off the line quickness. Most of the fun is up to 40 anyway. Im already swapping in 4.10 gears so that should help some.

 

This is a quote from your previous post:

"i stomp most rice rockets off the line and up to 85mph, I can have 6 witnesses with me to confirm that.."

Where do you live that has roads with stoplights, and the speed limit is 85MPH?? This would have to be the case since you claim that you don't break any laws!!!

 

Actually there is an abandoned airport about 5 miles away from my home where people go to test their cars. Its a mile long strip. Since this is on private property and the owners do not seem to mind as they join in on the fun sometimes, this is not against the law.
