dyno tuned 3071
 

Well folks, drove up to Ken Hill's place up in PA to get the link dyno tuned. I've just recently finished the FM2 upgrade to a 3071R and 750's with WI. Ken is a super nice guy and really knows the Link ecu well. We did probably 25 pulls and below is the best we could get. This is at 16psi. Where is the damn power?????

Post you ign map.

post your spark table.
Any exhaust leaks before or after the turbo? (I had a leak at turbo outlet and couldn't make more than 8psi)

If the red-line on the AFR chart is 14.7, you're in deep shit.

and on a dynojet to make matters worse

It looks like the red line on AFRs is 13???

Closer, but should still be about a full point richer.

EDIT:

nm...the WI part didn't click.

I'd like to see a boost chart as well, for how long is it holding 16 psi, and when?

Fuel looks like 12:1, hard to tell, but might be a touch lean.

Keys to success:
Remove Link
Add MegaSquirt
Tune
????
Profit

Link = fail. I bet there's at least 30 whp on the table.

New ignition will help too. Ima make a thread about that.

post up your timming chart dude you are probably way conservative how much water are you spraying?

Add fuel, get detcans out, add timing, make over 300rwhp or die.

We couldn't bump the timing anymore without knock. He wanted more spray, turned up the pump, duty cycle. I had the smaller of the two jets that came with the kit, should have put the big one in but didn't have it with me, didn't really think I'd need it. I'll post the tables asap. We ran the boost up to 20 but it was blowing out the spark. I had planned on having the cops installed before the dyno but.... still waiting on them. The 750's are absolutely idling, would have been fine with the 550's but I have plenty of room for growth.

what's a detcan?

Something you learn about on google like the rest of us....



It's a mechanical way to amplify engine noises...especially knock...using a flattened brass tube bolted to the head, attached to plastic tubing connected to earmuffs.

You can distinctly hear detonation onset over regular valve noise about like hail on a hot tin roof.

detonation can used to hear what your motor is doing like a stetascope but stays on the car and can be heard while driving. Put the bigger nozzle in what size are you nozzles anyway? Give me a size and i will help you.

epic fail!

Here's the data

So you're hitting target boost a little after 4Krpm?

Something is def. wrong with your setup. Back to the drawing board.

gotcha, knew of it but wasn't familiar with the detcan term. I am logging knock with the knock sensor, not flying blind. It retards the timing if it hears knock. We ran it up to the knock point and backed off a hair on the dyno. Water definitively helped reduce the knock to a point but again, needed a bigger jet. Looking up the jet size now.

wi jet is a 6.2 GPH

I don't see where you describe your exhaust.

What kind of dynojet is this? I am taking by context that it does not have a brake. I thought Ken Hill was a decent tuner. Your account of events, taking pulls and watching the knock sensor, does not instill confidence.

Link is old. What about your mani and dp, current gen stuff or old?

And that is quite a bit of timing.

Is there a way to produce a table of total advance vs. RPM vs. MAP from the Link?

Pull your valve cover and front covers and make sure your timing isn't fucked up. You should not be detonating with a 3071 and water. .64 A/R?

edit: you're idling at 39kpa? Isn't that really, really shitty?
