If you're on the fence over the PnP, do it. I've had the MM9495 running my turbo for a month now as a beta tester, and I've been thrilled with it. Stupidly easy to tune, so even a total moron like myself can do it. Easy to set up, easy to install, couldn't be happier with the ECU. It was the easiest part of my entire build.

Savington wanna give us a simple break down of tuning?

sorry

Damn't, I could have saved 30 bucks. I begin tuning my car very intently today, so I guess the 30 bucks was worth it.

I went and had it done professionally. Jerry actually tuned my car himself at the west coast MS meet down in LA a few weeks back. They did it static-load, which meant one guy (Scott from Spectre, IIRC) adjusted the manifold pressure with his right foot while the dyno held the car at a certain RPM. Jerry then used the tuning screen in the MS to adjust each cell's fuel. They probably had it dialed in within half an hour. It's at 11.8:1 on the top end, which is a tiny bit richer than it could be, but for what I'm using the car for (extensive hard track use) it's perfect. They then made a few pulls, set the timing in very quickly (advanced until it made less power, then pulled back a couple degrees)

As far as road tuning, you'd start by taking someone else's maps (something close to your application), and then setting the Req Fuel to your injector size and going from there. You can either make repeated pulls, using the Megatune datalogging feature (way, way more powerful than I could have imagined), or you can enable the autotune feature to get you mighty close, and then datalog to get you all the way there. As far as the spark, the best way is really to do it on a dyno. You need to be able to see power numbers to know whether your changes are helping or hurting.

The Megamanual is a huge wealth of knowledge about all of this stuff as well. There are quite a few people on here who have roadtuned their MSes.

When will the 94/95 basemaps be released??

can i tune with the WB02 enough to autox?

Dyno time is hard to get, I would like to get it, tune fuel, autox then do the timing after i finish my turbo next summer.

Probably in a day or so-- I basically just need to post it...


Are you N/A now? Relatively stock? Stock injectors still?

If so you really won't have much tuning to do, and a wideband will be all you need to fine tune it if you take your time with it. Basically just make sure the AFRs look right under idle and cruise. And then at low, medium loads, and WOT, at all RPMS. If your setup is that close to stock then the base ignition map is going to feel pretty nice... We left a tiny bit on the table in the name of being conservative since I don't know what fuel you'll be running, but not much.

I still havent dyno tuned mine loki and it runs great,

I really can't stress how good a solid steady state dyno tune will make your car feel-- better than anything you can do on the street, particularly with ignition... I've tuned quite a few cars on the street, and more recently on a steady state dyno, and I can attest there is a difference... BUT, if your car is close to stock, our base map is going to be so close that it will make little difference. In fact, if I were to dyno tune your car N/A I'd probably skip tuning the ignition and tune the VE only as I've already nailed a near perfect N/A ignition map for this motor... Heavily modded N/A may be a bit different story, minor mods won't effect the ignition needs too much. VE will need to be fine tuned though...

Wheres a good place to put the IAT temporarily till i get my IC piping done?
Is the map sensor wired into the MSPNP?

karter74

iTrader: (4)

Well, I can't wait to test out the base map on my car, post'em up!!

Does the LC-1 fit into the stock O2 bung?

FoundSoul

iTrader: (5)

You can leave the AFM in place which has it's own IAT until you do the IC piping...


The MAP Sensor is internal to the MSPNP, there's a nipple on the side of the box.

The LC-1's sensor will fit in the stock o2 bung...

Loki047

iTrader: (6)

yeah but then i would wait to buy the MS too :(

Is there a way to disable the flapper door and use the AFMs IAT?

FoundSoul

iTrader: (5)

I suppose you could lock the AFM door open... but the other option is to weld (or jb weld) a IAT bung in the current intake tract, just before the throttle body is ideal, and put the IAT sensor there.

Loki047

iTrader: (6)

Well the metal bungs arent a big deal to get, just pipe thread. Ill jb weld it right before the TB. (no where to weld on the stock intake tract)

FoundSoul

iTrader: (5)

Take a look in the manual too-- for NA you can just weld it on a 3" pipe and put it where the MAF used to be... there's a pic in the manual.

Jerry!!!!!!

Could use those maps tonight if you get a moment to load them up.

Order placed. Jerry please check your PMs.
