ATI Procharger, running actual 6# of boost.

You guys are all correct tuning is the key. I am very happy so far. We shut it down at the Dyno at 4600 rpms because it was getting lean. I will be putting in 42# injectors tomorrow and purchased a LM1 A/F meter with the rpm hookup to have more accurate tuning starting next week. Then back to the dyno.

Dynoed 448.1 RWHP and 471.7 RWTQ.

My old best was 392 rwhp and 378 rwtq. Who would of thought tuning my car would give another almost 100 rwtq.

There is a lot of power sitting there from 2800rpms - 4000rpms because the car was running very rich at that range killing the power.

I am really happy.

I do a lot of reading here and all of you have been a big help, special thanks to James at Diablo Sport for the tuning he has done thus far.

To see the day where you email tuning back and forth for a car just amazes me.

Very Nice!!

Yep, I also learned it's all in the tuning . . .

So to tune with the LM-1, you need the LM-1, the aux cable #2, and the inductive clamp? Which is $350 + 99 + 20, right?

Nice #'s



You don't need the inductive clamp. You can just tap into your tach signal at the pcm and run the line to the aux cable. Thats what I did and it works great.
It's so nice to know what's going on with the A/F vs rpm

Todd2001SS

I am not getting the clamp, maybe I will for 20 bucks more just in case...I hate not having something I need. The person told me from Innovate who sells the LM1 that you do not need the clamp. I am not sure where to hook up the rpm cable but will find out next week when I receive it.

Honestly I see no other way to tune a blower correctly without a A/F meter unless you have a place at a dyno shop that tunes LS1 cars. In Seattle there is no one that tunes LS1's, so this will work perfect for me to send infor to Diablo Sport and nail it down. Then I can tweek it when I want. Spending $150 at a dyno to see if the A\F from the tune is correct each time is nuts. This will pay for itself.

Hard to believe I was sitting on all the power without a tune. Plus now I will be running the motor a lot safer.

Ditto, I have my LM-1 installed now and no longer have to go to a dyno session to get an a/f graph. I just can go to the track and pay 10 bucks to get as many WOT passes I want. $$ in the bank if you ask me. I also got my LM-1 from a member here that used it once to tune his car and sold it to me for 265 I can't wait to start logging info at the track or anytime I am on the street and send that info to NoGo so he can fix me up with another "email tune up"

Todd2001SS

I have not received mine yet but where and how did you hook up the rpm part of it?

Sorry just read the above.

I agree. Which wire is it? Thanks.

Pin 10 (white) Connector C2 Red.
I just used a quick connect splice on the wire about 5" from the pcm. Than ran a wire through the grommet in the passenger side firewall under the pcm to my aux cable's rpm input. Plug the cable in to the LM1 set the default in the software to read rpm and your good to go

Just checked out your car domain pics. Very clean and holy bling
I see your using the ATI supplied FMU. Word of warning. Keep your eye on your FP with that. Mine took a poop out of nowhere. Ran 70psi when it was working but dropped to high 40's when it crapped. Opened it up and the piston inside had a build up on it that was keeping it from moving up and down freely. Cleaned it but a week later same thing.

Thanks a million for the info and compliments.

Those pics are old, I removed the FMU, it was causing to much trouble. The FMU never worked correctly with more than 3# of boost, it would hit 85# of FP and kill the car with fuel at 3k rpms or so.

Again thanks I will check out the wires tomorrow to plan for the routing of the LM1 rpm wire.
