Well I am comparing my last dyno log to this log and I see some things that interest me. I am new to efilive and logging stuff so this might be something it might not???

I think I am maxing my MAF a lot faster with the FMIC than with the twins, here are the readings:
RPM=5166+, MAF lb/min 62.74 MAF gram/sec 474.34 FMIC log

RPM=6155+, MAF lb/min 62.74 MAF gram/sec 474.34 TWIN IC's

IAT's look a lot better, temps with the twins on a WOT pass went from 97deg to 120 degs.

With the FMIC they were 81deg to 91deg at WOT(60mph to 93mph) with outside temps at around 82 deg's this morning. It took 2.14 minutes for the FMIC to cool the IAT's down from 91 to 81 deg's.

IAT's stayed around 71 at the beginning of the trip until I started getting into the gas a lot, then they stayed at 81 for the rest of the trip(with the execption of WOT). The FMIC was soaked at the beginning of the trip due to a rainstorm last night to add that in, so that's probably why the IAT's were less than outside temps at the beginning of the trip.

My a/f at WOT looks to have leaned out from 10.1 down, to a 11.1-1-10.9-1.

Boost, who knows, my digital boost gauge was reading 1psi lol. I didn't have a chance to change it out with the rain yesterday.

Thank you, Frank for watching the laptop and LM-1 when I was driving

Oh yeah, I thought 98 MAF's freq limit was 11500 ish? Mine keeps going up to 12554 on the freq scale??? What gives there?

I will be logging track passes tomorrow to see the affect of a whole 11 sec 1/4 mi pass on IAT's

Blackbird

they scaled your MAF table thus it reading to 12554 and 62.

stock it would stop at 58.1 and 11500

all in all sounds like the FMIC is kickin ***.

what does the butt meter say ?

aaahhh that explains the MAF numbers, I thought mine might be broke...
The butt meter sez But I will wait till tomorrow for some proof of that. I just hope the track is hooking It's a more responsive to the ol' throttle now, and its breathing a lot easier, me and my dad were looking for a leaking IC connection for about 10minutes just to find out that it was the airfilter making all the "sucking noise." Its loud from the passenger side and even louder on the driver side.
A poor LS1 SS tried to "pass" me on getting on the freeway, I proceeded in putting about 16 cars on his *** in about 2 seconds lol, then he did a ricer fly by as I was coasting down I love my car My buddy frank got to witness the LS1 ricer fly by too, talk about hilarous, his wife or GF probably asked why he couldn't make it past my car when we both exited the on ramp, hope I see him at the track

Sounds good. What is your maf reading at 5166rpm before the FMIC?

Did i read that right, the FMIC leaned you out?

Lookin good Jer. I recieved mine today. Time to order other parts....
Get that Mech. boost gauge fixed before tomorrow night....

BlackBlown, Let me look the logs over and I'll post up. What I forgot was that this was the latest tune from NoGo This file was leaner all around so that's probably the reason for the before and after WOT a/f readings Sorry about that.

How's she look, pm me some pics and YES SIR! Boost gauge will be ready or I will shoot excuse making self lol.

BlackBlown, here is the closest line to 5166rpm on the twin log.
RPM=5209 MAF lb/min=52.87 MAF grams/sec=399.67
What does it mean? Good or bad?
thanks,

My other computers down but i can email them to you... along with another toy i got today........

Sounds pretty good to me! You gained roughly 100 hp worth of air at 5200rpm!

2001WS6Vert

Weren't you the guy that was going to cover up the intercooler on the street because you drive like an old man? What's with the 16 car thing? Man you've got me thinking about options, I see 160 + IAT's putting ice in the reservoir until its cold ice water. I think I'm overwhelming the Vortech aftercooler.

Black Blown, Damn that's great to hear, I knew the car felt stronger lets hope that she puts it down at the track, you have me stoked to no end now
even if I gained 50-75hp I would've been happy

Kyle email me the pics jsbird1998@comcast.net

2001WS6Vert, Yep I'm that old man, and damn am I busted lol. Easily 16 car lengths, stock LS1's run 14.5-7's up here in ALB, I run mid 11's Poor dude didn't have a chance, he shouldn't have tried it, my car doesn't sound stock at all lol, the road was wide open, and visibility was at 100 percent, no cops around Plus I was feelin kind of good with how nice the car was running on our lil logging mission, can you blame me I had too
The cover is off for good, after looking at the mesh all day I got use to it and the lil woman likes it better that way too
I'm happy with the big FMIC, the IAT's really stayed low. Tomorrow I will have some 1/4 mi passes logged to see if they go up considerably more for a full WOT pass.

J[/QUOTE]

Maxing out the MAF earlier makes sense... if your IATs are cooler, the air is more dense, hence more mass.

That would also explain your WOT A/F leaning out. If you max out the MAF the ECU still feeds the same amount of fuel even though your air flow increases so your A/F leans out.

Jer i emailed them to you........ im off to bed now ill check this out tomorrow..... i have to get up at 4am........ Hope all goes well at the track tomorrow. Shoot me a reply to my email.
Later

Nassau, cool looks like everything is playing nicely in the ol PCM, it could be a lil richer at idle, but other than that the car runs STRONG. I was figuring more power(air) to lean it out up top, but didn't have anything to back that statement up(dyno sheet or timeslip) I'm liking what I am reading from you's guys, more power more power, now its up to the car to show me at the track

Kyle, you got mail, those are nice

Man, this FMIC thing is a good mod! Your results are similar to mine. I gained about 11lb/min at 6000rpm. You probably gained quite a bit more at your redline because of your increased flow.

frcefed98

iTrader: (16)

No joke, the FMIC really helped out a ton, plus I went from ATI's 10ft(no exageration) of 2.5 inch IC pipes that were coupled with radiator hose connectors that expanded like balloons on the dyno to, 3 inch very short and direct IC pipes with reinforced 4 ply silicone couplers to join stuff together and 3.5 inch pipe after the MAF to the TB. You can easily fit 3 of the ATI twin cores on this FMIC plus have some left over lol. I hope I see nice power gain near my redline of 7100rpm.
I am glad I did it, the wallet isn't tho I need to find a job quick

Since you changed your whole intake setup the MAF numbers are going to change quite a bit so you really cant go off of that now. When you hook up your boost gauge that will tell the story, smart idea having a wideband in the car - no FI car should be without one

frcefed98

iTrader: (16)

KP, I knew it was too good to be true, hopefully I get a nice gain tho, its all freed up and flowing awesome. Yes, the wideband is awesome and I ran the car FI'ed without one for too long, I was truly playing russian roulette with the car back in the day. I have it next to me anytime I'm in the car. One day I will be able to utilize all my logging, editing, and WB capabilities to their fullest, but man is it overwhelming

Part of the fun is figuring all that stuff out

I'm sure you gained some with the FMIC, if you were using the exact same inlet tract you could use the MAF as a guide but obviously you didnt. The IATs look pretty good considering you are spinning the blower pretty fast and I'm sure you will see a nice gain with FMIC and better pipes.
