New software release - AUTOTUNE IS HERE! - Genesis Forum: GenCoupe Hyundai Genesis Forums

**DynojetResearch** · 03-05-2010, 06:42 PM

The wait is over! AutoTune has now been officially released for the Dynojet CMD. It requires that the CMD also be connected to a Dynojet WideBand 2, so if you don't have one yet, don't forget to mention you are a Gencoupe.com forum member to get your 10% discount.

For those of you that already have the WB2 installed and connected, upgrade to the newest release version of software (1.1.5.3) and firmware (1.4.4) which is available on our website here: Dynojet CMD downloads.

Now comes the fun part - the Master Control Center (MCC) software will now have some new features... When you connect your CMD, click DEVICE TOOLS, then CONFIGURATION. You will find a new tab for AutoTune.

First you need to put an X in the ENABLE AUTO TUNE box. Then, the other options are:

Require Run Time – If checked, this is the minimum run time (in seconds) before the AutoTune will “turn on.”
Max Enrich Trim – the maximum amount of adjustment the AutoTune can make going richer. This ensures that if the sensor went bad or something went wrong with sampling, that it could not add more than this percentage more fuel.
Max Enlean Trim – the maximum amount of adjustment the AutoTune can make going leaner. This ensures that if the sensor went bad or something went wrong with sampling, that it could not add more than this percentage less fuel.
Max Sample Lambda – this is the leanest Lambda reading that the AutoTune will attempt to richen up. Leaner Lambda values will be ignored. I picked .92 for our car as once the car enters open loop operation, it’s always quite rich in stock form. This ensures that it’s gone rich before doing adjustments.
TPS Filter Enabled – If checked, it looks for TP rate of change. If the rate of change exceeds the value in the box, it will stop AutoTuning for the preset amount of time. These are somewhat arbitrary numbers. You will need to log a drive session to see what kind of numbers you want. I found 2500 works well for our car. Log a run while you're playing with the pedal and look at TP rate of change to determine the set point for your car.

When you hit OK, the config will be updated. Then it will want to get the map in the CMD. Once that happens, you will see two new tables in Control Center. They are Target Lambda and Trim. The target Lambda table is where you put in your target values.

Remember that Lambda is related to A/F. Stoichiometric for gasoline is 14.7:1, so Lambda is 1.00. To determine what Lambda value you want, divide your target A/F by stoich and that will be the Lambda value. So 11.5 / 14.7 = 0.78 Lambda. Just like your fuel table, put the target values for the RPM and MAP cells. Determine the voltage of MAP where the car is on boost and in open loop. Check it based on logs and your findings.

The trim table will be populated as you drive. When you next do a get map after some driving, you will see values in the trim table. If you right click on the trim table, you will see the apply options to apply to the base fuel table.

If you have any questions, please send all correspondence to tech@dynojetcmd.com

Good luck and have fun!

Awesome

Now i really cant wait to order my CMD and WB2. Keep up the good work guys!

whatnot · 03-05-2010, 11:09 PM

Well, done, looks well worth the wait.

Zoile · 03-08-2010, 05:44 AM

So with this we don't need to play with map values, it will tune close to what is best and safe for the car?

whatnot · 03-08-2010, 08:36 AM

dynojet will need to confirm this, but since they are not on atm, I will give it a shot.
You still have to set your MAP/TIP values, its not that hard. All this does is reads your WB 02 and adjust the fuel DC from what it is to what you sad you want it to be to obtain said Lambda. This has nothing to do with MAP/TIP clamps.

The only way I think this could help you set clamps is that it allows you to underclamp and the AT will compensate for the fuel, though due to timing issues ect. I don't remccomend severly underclamping. Just drive log, and place clamps, if you still get a CEL, back your highest clamp down .1v and keep driving untill you no longer get a CEL, then your clamps are set, and you never have to touch them again.

Zoile: Setting map clamps is pretty staight forward though, check the DynoJet website under the downloads for a MAP/TIP clamp tutorial. You basically log a couple WOT runs, open MCC, create a new histogram, play back the logs, copy max tip/map values from the logs into the MAP/TIP clamp fields. Takes about 5 minutes.

**DynojetResearch** · 03-08-2010, 08:45 AM

whatnot has it right. The AutoTune will fine tune the fuel curve to hit your target air/fuel ratio set in the target table. It does not do anything to the clamps or boost tables.

Zoile · 03-08-2010, 09:05 AM

Ok, thanks for the help guys.

Deatschwerks · 03-08-2010, 09:15 AM

great product

quillero20 · 03-16-2010, 08:32 AM

how can i dyno tune my car in the miami area ?

**DynojetResearch** · 03-16-2010, 08:46 AM

The only shop in South Florida that I am aware of that is tuning with the CMD's currently is Velocity Factor in Boca Raton.

Here is the page to look up your nearest Dynojet dyno center, but I can't tell you who on the list has experience with the CMD directly. Dynojet Automotive Dyno Centers

quillero20 · 03-16-2010, 09:32 AM

thank you i will look it up right now

quillero20 · 03-16-2010, 10:59 AM

hey what's the best computer for the 3.8 ?

**DynojetResearch** · 03-16-2010, 06:54 PM

We don't offer anything for the 3.8 V6 yet. We are working on one though.

So you finally got a V6 to work on? That's awesome news!

**DynojetResearch** · 03-17-2010, 07:48 AM

Not exactly. Our engineering dept. in Montana got one to take a look at and design a harness. The testing will have to be done here in Vegas and we do not have access to a car here yet.

quillero20 · 03-17-2010, 08:59 AM

nice let me know as soon as you find anything for it please

whatnot · 03-17-2010, 09:35 AM

were you able to get a hold of GenCoupLV? Or did anyone tell you he has a 3.8 in vegas?

**DynojetResearch** · 03-17-2010, 10:32 AM

I believe on his introduction post we asked him if he was interested and never got a response. He has not contacted us either.

Slider · 03-18-2010, 12:05 PM

I will ban him.
