Tune?

306N/A · Jul 2, 2014

Running 360-400 hp 306 , runs good but should I get a tune or chip for the al9 ?

Sharad · Jul 2, 2014

There's no substitute for a good custom tune... but it gets complicated since the EEC4s can't be flashed like the new cars. I've used an AFM PMS in the past, and that was a suitable option. Many people upgrade to a standalone like FAST or Holley when they want to tune a Fox.

So much information is missing from the original post. Mods? street, track? what makes you think you need a tune?

Spaz · Jul 3, 2014

Has it been on the dyno already? If so, does it have 360 hp or 400 hp. 40 hp is a pretty big difference. I presume you have forced induction of some kind.

If you think it runs good then rock and roll.

If you want it to run better, find a reputable tuner and have them burn a custom chip for it. (not mail order)

Ya runs good, but not sure if getting a chip or tune will give me noticeable difference?
Was on a engine dyno. Added few parts afterward
Noticed it doesn't let me rev past 6200

could be a lot of things from the cam to fuel to timing. You need to post more of your setup. Where does peak hp and tq occur?

The stock EEC doesn't let it rev past 6200 I heard, acts as a rev limiter ?
Just wondering how much power can the stock EEC handle till it has to be upgraded or if it even has to?

Went to the strip Friday was running 13.1 with no traction off the line. And had mt street slicks
Where should I go from here what would be my weakest link?
I'm thinking 410 gears ? And is the cobra intake restricting flow?

That's a pretty mild combo that I doubt is laying more than 300 to the wheels. What cam are you running? With that combo your ecu should have no problems running things. Don't waste on a tune.

2000xp8 · Jul 6, 2014

Most of these setups don't need more than 6200rpm.
You say you need to go past 6200rpm, yet have a cobra intake. My guess would be you really don't need to go past 6200.

Your mph along with your ET and 60ft will help determine if it's the car or you that is the problem.

Intakes aren't responsible for a missing 1-.5 seconds.
Maybe .2 at best with a 306 with another intake.

You don't need 4.10's or 4.33's.
3.73's are fine for most street cars.

Comp cam fw 276h-r14.
At the end of the 1/4 I'm in 4th at 5000rpm with 373.
What gears can I go to 410 433?

306N/A · Jul 6, 2014

Rt - .411
60 - 1.956
330 - 6.062
1/8 - 8.375
Mph - 84.87
1000 - 10.88
1/4. - 13.011
Mph. - 106.34

Could not hook up in 1st. Track was horrible
And was my first time at the track.. So ya I'm big part of the problem

2000xp8 · Jul 6, 2014

Your 60ft time isn't that great for using ET streets.
106mph is a little low too.

I'd guess your issues have more to do with driving and practice and your setup. Rarely does anyone pull their best run on their one and only try.

If you can't hook up now with 3.73's, it only gets worse with 4.10s.

I agree. Work on your driving skills. Sounds like you are spinning through the 60ft. A deeper gear will onlly make it worse.

Couple of questions

What is the air pressure in the tires
how much of a burnout are you doing
what rpm are you launching at

They make new pistons every day, so why worry?
