Fired my engine on the PRO firmware today.

[614streets]

Took a delay and time to correct a problem that arose but I finished converting the engine from narrowband commander 950 control to full closed loop "PRO" Wideband run in series with my tech edge v 2.0.

I was given the new Pro software upgrade from Holley before it was released to the public(still not available).

Ive set it up for now to run 12 a/f ratio under boost , full closed loop.
Without a cog belt the best it can muster is eight lbs five of which can be seen on the gauge off idle in nuetral.

So are you beta testing it for them or something? Im not sure what the tech edge 2.0 is, or what the deal is with boost without a cog belt (are you running rubber bands to it:P ). I hope to run a wide band for tuning purposed this year. Brad was showing me some cheaper LED readout options but recording would be priority for tuning.

I believe the cog belt (like a timing belt) would be needed to avoid the supercharger belt from slipping under load..

Yeah its turned by the 6 rib serpentine belt so with out a 8mm cog belt it does slip a little.

The Tech edge is my wideband controller , basically I have it on the truck and its now sends the wideband signal to my Holley Commander and the commander inturn can see what the true a/f ratio is and make the adjustments all by itself. Of course the base map still has to be close to help the commander from having to compensate to much add or subtract values from the base map to obtain whatever a/f ratio I have chosen for the 8x8 target matrix map based on RPM and MAP(LOAD).

One of the other features of the PRO is I can set the cell values of the maps to whatever I want , before it was preset resolution , now I can have more resolution on the actual map/rpm areas the engine is run. For instance by selecting a 2 bar setup selection for base map resolution on the regular commander , the load scale goes all the way up to about 15 lbs of boost , but since I am running 8 lbs I can scale the map to show up to 9 lbs and by doing so I get more base map values or resolution to program within 0-9 lbs than I do with a 0-15 lb map because the map for programing is not Infinate.

[SappySE107]

Auto adjusting is always nice So will it save the new values for you as well or do you still have to adjust the tables after watching how it works.

[614streets]

The commander ecu itself can adjust the base maps to obtain the specific a/f ratio I choose. The amount the ecu can adjust the base map values is also programable in a % value. In other wrods Once I set my base fuel map with the amount of pulsewidth needed to maintain about what a/f ratio I want on that area of the map (RPM/LOAD) I can program what A/F I want the commander to "adjust" that pulse width value to maintain the a/f selected . The amount of fuel added or subtracted by the ecu to maintain the desired a/f ratio is adjustable. I have my lower setting,(4 area target based on map) the two lower map ranges the ecu is capable of adding or subtracting 25% of the base map , the top two where the most load is encountered I have enabled the ecu to add up to 25% to maintain the desired a/f ,[b] however I have the amount of fuel the ecu can remove at that range set to 0% to ensure the computer never tries to take fuel away . That ensures I could only end up slighly richer than desired underboost ,but never too lean.

Very cool How much does that setup cost? How is it setup for spark, if at all?

[614streets]

Full spark control has spark map. A holley ecu is only $500 , wiring harness is extra, etc. The new PRO unit should be available at Jegs/ Summit in a couple months. The Tech edge wide band for TE is $385 comes with a nice led display, it also is flashware and I like it alot.

[SappySE107]

cool, sounds like a good deal for someone not inclined to use the stock ECM:P How did you get the Pro unit already? You didnt kill anyone did you....hehe

[614streets]

No no, lol. Doug Flynn at holley emailed me and upgraded one of my commander 950's to the NEW PRO version about 4 months ago. Its cool the book on it says on the front, "I sent you the new unreleased PRo version". I plan on showcasing that someday. And best of all he did it for free , can you belive that?

Needless to say I am now a dedicated customer of Holley.

[614streets]

Only other guy I know of that had the PRO version before me has a 1500 hp 1965 Nova.

damn, nice deal...

so its an easy to use setup? so with the Holley ECU your using, the Tech Edge wideband just plug and plays with it? as it takes the signal output from the TE and the Holley ecu uses it as a input..

i have been looking at this for a wideband setup: http://www.innovatemotorsports.com/


so this is your WB setup then? http://www.techedge.com.au/vehicle/wbo2/default.htm
interesting..

[614streets]

Yeah thats it. Yup easy to use. Yeah the Holley ecu is great it is programable with any aftermarket wideband controller. You just input the values. Tech edge is AFR= AFR-9/2

I like the Techedge dude, I suggest it over the Innovate. The tech edge comes with a Nice LED display so you can read the true a/f ratio as you drive(Innovate lacks that) and the techedge is always improving, you can reflash with newer firmware over the internet as they do continual testing to make it as accurate as possible, also the tech edge unit allows you to free air calibrate your sensor whenever you wish, pull sensor out of pipe , software runs test to read free air then you note readings and calibrate it .

[v6h.o.]

thanks for the advice. i'll look into the Tech Edge a bit more. i think i remember seeing an Ad or even a write up on it in one of my australia car mags i brought home.. have too dig through them.

been looking at the Holley unit. (its dead at work right now)
seems pretty cool and simple to use.
doesnt actually say it but it sounds like it should work for DIS Ignition systems:

Timing control function can be achieved through the use of:
..........- Small cap computer controlled GM HEI (stock GM or Holley PN 890-160).
..........- Large cap computer controlled GM HEI.
..........- Ford TFI distributor.
..........- Magnetic crank trigger.
..........- Hall effect crank trigger.

so the regular commander 950 software is just setup to run regular "narrow band" A/F ratios, the PRO upgrade is where you can run it and tune it with with the advantage of the wideband setup?

Looks promising. im looking for something around the 800-1000 range as i just know nothing of tuning with GM code to tune my own chips.

Here is one of the ones I just recently have and am very intersted in...
