Also resistors are not the best way to run low impedance/peak and hold injectors. I bought and built a peak and hold driver for my van.

Why reuse anything that's 30ish years old if you don't have to? Buy the injector plugs and build a new one.

I got an under hood relay/fuse box from a '95 Caravan and wired that in.

Megasquirt controls the fan. It might control the alternator. I read that it can't control the alternator so I went the external regulator route but after I started tuning I found a section in...

I don't think the Ford 2 wire IAC is any good. Chrysler uses a 2 wire PWM valve on the 2.4 that might work better.

I think you are correct about the 4 wire IAC. Sometimes it'll be fine and other times it seems to "stick." When it's idling high, if I go under the the IAC test and send it to "home" position the...

Like I said:



You are definitely more knowledgable since you're one of the pioneers and have probably forgotten more than I know about the factory set up. I really wanted to get rid of the 25+...

Just because you take it to somebody else to tune it doesn't mean things can't go wrong. Granted the more experience someone has the less the chances of mistakes are going to happen. I had a...

Honestly I think you're over your head. You think spending more money on an EMS system is going to save you from destroying your motor and you're wrong. "Garbage in, garbage out," it comes down to...

Self tuning is only for A/F ratio. You have to come up with an ignition timing table. You set your A/F ratio for MAP & RPM in AFR TABLE 1 (for example you set 14.7 at 10"HG and 11.5 at 15 psi of...

Why is using a MAF a plus? MS is capable of using/reading them. Not sure why you need to?

On my 2.4 I'm using 2.4 Chrysler Cam and Crank sensors. TPS and IAC are 2.2/2.5 Chrysler. IAT and CTS are GM style sensors from DIY AutoTune. MAP sensor is built into MS. I also wired for a...

Also, for those that are use to the Chrysler cals, there are no part throttle or WOT tables. There is only one fuel table. Well there are duel tables when you're using E85. When you hook up an E85...

There was a member here that was going the same route I was and I tried pass on everything I learned to try to save him time and money. He didn't have the money to go my final path, which is...

I heard the same thing. I was able to idle 120pph/1260cc injectors just fine on my 2.4 with the factory '89 SMEC (batch fire) on either 91 octane or E85. Actually I should say Harry had no problem...

That mistake can be made wether you spend $400 or $4000. The only difference is if you spend $400 you have more money on hand to spend to fix your f-up.

If someone had to fab their own adaptor I'd agree with you but with Rich selling the adaptor AND the modified distributor the 2.4 swap is a breeze. The only drawback for me was blowing the spark out...

I bought MS3/MS3X assembled, 4 bar map daddy, knock module, two 6' wiring harness', P&H driver, the big weather pack kit, coolant temp sensor, and air charge temp sensor from DIY AutoTune and I spent...
