[Iowa99GST]

What's the difference? Pros & Cons?

Thanks guys.

Let's not take over the OP's thread. PM me with your questions and I'll try to help you out.

MAP = Manifold Absolute Pressure

Not to be patronizing here, but for general info...

There's a computer in your car (ECU) that tells the engine what air-to-fuel ratio to shoot for under varying operating conditions. Unless you put the pedal to the floor, that ratio is 14.7:1... which means a ratio of 14.7 grams (or moles, or pounds, or metric tons, or whatever you want to use) of air to to 1 of the same measurement of fuel. In a nutshell, that ratio is determined by tables in the ECU based on RPM and engine load. Unless you are flooring it, that ratio is 14.7:1. If you go WOT (wide open throttle), the ratio changes depending on engine RPM and how much load the engine is seeing.

NB sensors are designed to measure AFR around a very narrow range centered on 14.7:1 which happens during idle and normal off-boost crusing. Wideband sensors measure true AFR over a much wider range, specifically at WOT where we really want to know what is going on.

The ECU typically commands an AFR of 9.5:1 or so when you mash the go pedal and go WOT, as defined by look-up tables in the computer. A wideband sensor will show you that this is actually happening. But you still need a way to change what the ECU wants to see...that is where tuning software comes into play.

ECMLink replaces a chip in the ECU with a custom chip, and allows you to change those hard-coded lookup tables along with many other things. If you would rather your engine shoot for an AFR of 12.5 at 3000rpm under a load of 3.1, you can. You can tell the computer to target a specific AFR under different conditions as well as many other parameters such as ignition advance, etc.

ECMlink and most other tuning solutions include both the hardware (a chip replacement in the ECU) as well as downloadable software that can be installed on a laptop or any other computer. In fact, you can download and install the ECMLink V3 software and view logs from other ECMLink users for free, on virtually any Windows based PC.

Somebody else pleeease "tag this post as helpful" for Calan.
He deserves it !!! What a great explanation.

Btw i dont know of anyone successfully logging a 1g with turnerpro yet.

more then just "logging" is being done... here's shot of a data trace

OP,
I would look into using Ecuflash & The Ceddymod Bins with your car since you more then likley have Flashable ecu... Can't say anything bad about ECMLink But I'll be the first to tell you there is other options out there...

Their far more then just logging being done... here's shot of a data trace

haha ive porbably watched that video 20 times. Was that made by a tuners member? I imagine i'll be using Jackal for a while, because it does everything i need it to do. Plus lately they introduced a cell tracking patch. Also watching Werewolfs progression. But i have tunerpro loaded up with extended maps,etc. I still like the tunerpro logging ui. I wasnt aware people were logging with it yet.

Wheres all that action happening?
