So one of the great things I love about my car, is parts are relatively cheap for it. I bought a Cobb Accessport for it which most of you probably know is a flash loader that flashes the ECU with a new map based on mods. Well they recently came out with AccessTuner Race (free BTW), which allows you full control over tuning the ECU. Boost, timing, fuel, etc...You want 99psi, you can try. HEHE. You can imagine that this could be a bit dangerous if you don't know what you're doing. I'm smart enough to know that I'm not doing anything until after I go to a 1 day tuning course down in Portland at a Pro Tuner shop, compete with dyno testing.

Here's a screen shot of one of the wastegate sections:

 

Cobbs stuff is great, but really be careful!!!

This is one easy way to make things go BOOM!

If you crank up boost, you also got to do fuel & ignition.

 

You can crank the boost with the boost controller as well. So depends on how they program the ECU. It can be program with safe guard which will go into limp mode if boost and AFR is too high or ignition timing is being pull much. My old SupraTT was set up with boost controller, methanol injection and nitrous. It also has AEM EMS which can be hook up to a labtop for tuning and data logging. It 's fun learning if you know what you're doing.

 

Hey Vincent,

Could you tell me a bit more about that Supra sometime? I wasn't aware you had one, but I'm guessing you may have bought a very clean one through Daniel or something like that? Feel free to PM me about it if you get a chance. I still want to see that yellow 996 of yours sometime too.

To keep this reply at least slightly on-topic, that new Cobb stuff looks very cool indeed. I'm glad you're cautious enough not to mess with too much at once though...it definitely looks like an easy recipe for engine disaster in the wrong hands.

 

Sure anyone could use a manual or electronic boost controller, but would still need some way of controlling fuel, timing etc. This gives you the option of controlling everything. It's pretty much the same as the AEM EMS, but you don't have a piggy back device. You can connect via a cable to the ECU and modify a live map, or start with an off the shelf map, tweak it a bit, then flash the ECU....

 

There is a real learning curve when it comes to tuning. You need a good understanding of what each parameter really means, which sensor provides that info and how/what other parameters are affected by any changes. It took me about six months of playing with HP Tuners and asking for professional input before I was able to tune my car for the BIG cam, headers and 4:11 gears I put in it. Very rewarding feeling when you get it running like you want. With HP Tuners I was able to save files and revert back if I went in the wrong direction too. Do you have that ability with this?

 

I have the ability to load any OTS(off the shelf) map I want. Cobb has a number of maps based on stock to stage 2 maps for various bolt ons. So if I'm tweaking a map, I can flash the ecu back if something goes wrong.....

 

So when you refer to a "map" do you mean the actual file in the ECU or an actual map as a screen shot? In HPT a map would be a table for Air/Fuel Ratio, Intake Air Temps, Throttle position, etc. which there was no off the shelf maps we could take and insert without the other maps being affected in some way. I had to work with complete files that had many maps within. Therefore I did alot of file trading with others online or would send my file to someone better at programming to reveiw before I flashed the ECU. Seems like your program maybe more flexible in this regard.

 

Maps are files that are loaded into the ECU and contain everything. Boost pressures, timing, fuel, etc. Here's the page we go to for off the shelf maps as we call them. They are built for certain mods, cay year, California code requirements, etc....

Here's the notes for the map that I'm running:

With ATR now, you can load that map into your software program on your PC, tune whatever you want, say more boost, or more fuel at 3500RPM, save it, load it on the Accessport and then load it to your ECU. Or if you're running the ATR software on your laptop, you can connect to a live ECU, modify the tables, and save it directly on the ECU....Dicey stuff if you don't know what you're doing though.....

 

Impressive setup and support! Way more than I had just five years ago. Amazing how fast programming for cars advances just as quickly as everything else. I feel obsolete now.
