John,
Do you have the MAP sampling window set to 120* for 6 cylinder engine?

Great progress!

Remember, it will only run as good as you tune it. Garbage in, garbage out.... ;)

I put a lawnmower fuel filter on my MAP line, but I didn't see much difference. You'll probably need a canister to dampen the pulses.

Bigger makes MAP signal latency, small makes pulse-y MAP signal.

It's about finding the happy median.

Where are you pulling a signal from? It should be in the center section of the manifold, or anywhere under the TB.

He's ITB

Ok... the way I have done them is to drill a port in each manifold below the TB's. Make a 7 port junction block. Make all 6 silicone hoses the same length and the 7th fitting goes to the MAP. This averages all 6 manifolds into 1 signal.

Your saying he's ITB but all the pics he has posted are using a 930 manifold????

That torque is grossly wrong!!!! Mine came loose at that torque. I don't know why it's supposed to be and where I found it,

I must have mixed another install.

Doh...

For vacuum I am using small aluminum 6 port distribution box. I am pulling signal from back of throttle body. I'll take a picture of it later.
I retorqued pulley bolt to 123 ftlbs. I am still using the 930 Intake manifold.

Hi Dennis

Using stock setting. Should I change this to 120*?

John,

Yes, the 45* values will work but you can try something < 120* for a six cylinder to see if it helps stabilize the MAP signal. My values are actually set 80* and my map signal is very stable, no orifice or fuel filter installed and my MAP averaging factor is set to 95, meaning very little averaging of the signal.
However, my MAP sensor is located on the MS V3.0 circuit board and is connected to the manifold with approximately 5 or 6ft of vacuum hose which may help stabilize the signal.

Thanks Dennis

Spent a couples hours out driving and using the autotune feature. This is an amazing tool. Car is really getting dialed in. I have only been concentrating on low load, and cruise maps. I have to blend the the bins into boost. I am getting a bit of hesitation. Super Rich. Back out tomorrow. Still need to work on hot start. Car is running really well. Thanks to everyone who has helped.

If you have some good hills, that's the time to cover the entire map with VEAL tuning.

Don't be afraid of using it to tune boost either, it works great.

What's cool, is you can turn on filters in case you have areas that are tune good.

For instance, you can set the load filter to not adjust anything in vacuum areas so it'll tune only boost areas. Or, once I've gotten idle dialed in, I may put 1200 RPM in the min RPM filter.

You can set narrow windows of load and/or RPM if you have some particularly problem areas where the area of the map may be fine, etc.

Thanks for the info on the filters. I was wondering how to lock bins. Car is running the best it has ever run since I bought it 5 years ago. Can't wait to get into the Boost tuning. We do have some hilly areas around us. I know what I am up to this week.

Buy MLV, it's worth every single penny of $20.

Run a 30 minute datalog AFTER the motor is fully warmed, and work those hills!

Try to get high-RPM with low loads and low-RPM's with high loads (then vise-versa), all over the fuel map to can safely run the engine to.

Run it through MLV and let it propose you a new map.

Trust me, it's great.

The beauty of it is, it's collecting data to target a change. Meaning, if it's 16:1 AFR when your target map is stoch, it can calculate pulse width % change immediately. It also averages the times you crossed that particular load/RPM bin to make a good estimate of the final fuel number change.

Using VEAL, is only as good as you manage to "hang out" in the problem bins slowly changing the numbers.

You can set VEAL to "Easy", but it tends to overshoot trying to tune too rapidly. "Hard" and "Very Hard" requires spending a LONG time in those cells to get it to change.

That's the beauty of MegaLogViewer!

Nearly immediate tune change in seconds!

Off topic, but confirming MLV works with MS2, as well?

I purchased a copy of MLV yesterday. Haven't had a chance to do any logging. Hopefully tomorrow. I am really liking the MS3 Pro. Seems well supported also.

AFAIK, all MS
