Camaro SCT tune Vs HP TUNERS tune by Tampa Tuning

[Tampa Tuning]

On a recent dyno day, I met an owner of a 2010 Camaro with a 6 speed manual enhanced SCT hand held unit tune in the car. I compared the SCT tune with a base line mail order tune of mine, and saw where additional gains would be sought even before I dialed the car in specifically with a Tampa Tune.

The owner stopped by last week and I worked my magic on it.
The car off the bat had to be dialed in for to much commanded fuel calling for about high 11s-low12s AFR.

When I was complete, It had no knock and 12.6 AFR at WOT. Because it didnt have headers ( through the SCT tune seemed to be set up for it), I had to reduce the prior given main spark by 3 or 4 degrees in the .76-.88 G/CYL range to reduce knock.

The SCT unit provided an OK tune, but there's no better method of tuning than having the car in front of you on whichever system you choose. If you dont have a tuner around you, the hand held unit will give your car a differant feel over stock.

Im not sure how much the hand held units cost compared to a $280.00 full street performance tune of Tampa Tuning.

I can vouch for Phils abilities as a tuner. It was my car he worked on last Sat., and I am very pleased with the results. My car was running good before but with Phil's help it runs even better now. We did about 8 runs to get the tune just right, some a little hair raising! I was very impressed with Phil's attention to detail in making sure my car ran perfectly with what mods I have on it. Not to say that the previous tune was bad, it wasnt, but its even better now. Now I just need my LTs! Come on tax refund!

Thanks Paul. Once you get the headers on, I can add more fuel and timing

12.6 afr considered safe?

[Tampa Tuning]

at WOT, you target 12.7. I say target because that number is going to continue to move slightly up and down as air volume flows through the exhaust and is read by the wideband. The mid to upper 12's is where you want to be.

If your targeting 12.7, but commanding the car to be 11.6, and hitting 13.8 its time to find a new tuner.

HP Tuners is a great tuning option out there Camaro owners.

Its $649 for the pro unit with 8 credits. Add a mail order tune for $150 dollars with a total cost of $800. Divide that by 4 owners, and you have unlimited access to your car, and a mail order tune for $200 each.

Tampa, what is your logic in making changes to the high octane base table rather than the fuel mixture spark correction table for wot timing tuning (PE modifier table)? In the end you really come out to the same place but I was just wondering what your thoughts were.

+2 for Tampa.... phils ability... and rhino79 great tunners....

[mgoodbar]

I love my hp tunners... I have used it on several cars.. not my l99, but none the less I can scan and dig around and learn....... I dont have the pro I bought my hp for 499.00 with 8 credits... took car of my buddys Ls1 and is so nice to have the abilith to go in when ever we want and change stuff.. If he wants to go back to stock, it just a button click away.... any time any place...

[BowlingSS]

I use EFILive and I love it. Worth the money IMO. EFILive or HPTuners are both great tuning software.

i wish I had EFI to.... it would be cool I know both have great options... since i dont have the pro I cant make changes on the fly.... cant efi do that.. make changes wile you drive down the road??

[Rhino79]

No that requires a roadrunner pcm and that's for gen 3 stuff.

[mgoodbar]

owww... ok..... I jst assumed live = like driving down the road... that would be cool though..... come on hp tunners wee need a up grade lol...

HP Tuners is still in the process of working on version 2.24, but I thought they did have the real time tuning for the Camaro

Simply put, Its the methodology in which I was taught. I was taught not to go over the top in timing or lean it out for better numbers.

Ive seen alot of guys that load it up on spark and drown it in fuel to prevent knock retard.

Im willing to give up some spark and some fuel and keep the AFR safe at WOT.

I set my PE for the commanded AFR and dial in the MAF to make it happen. If I have to pull some spark in a certain G/cyl vs RPM range, Im good with that.

To tell you the truth, WOT is easy if your scanner is configured correctly with a wideband and a error percentage histogram. Part throttle fuel trims are harder and much take longer.

RTT would save ALOT of time of they did. HPT will be at SEMA next week, so im hoping they will break some kind of news of something special by year end.

I agree with this.

What I was talking about though was in reference to tuning the timing. On the E38 system, GM uses a fuel mixture spark table to add timing based on e.q. ratio. So you have the sum of the high octane table, the cam phaser timing table and the fuel mixture spark correction table. I usually use the fuel mixture spark table for wot timing because you can dial in certain timing changes for the e.q ratio you are commanding, rather than just based on g/cyl vs rpm.

I know in the end if you change the base timing map then you can make it all end up the same, just was wondering if there was a reason or if you were trying to stay away from the e.q. timing table.

I know a lot of the gen 3 pcm's in the f-bodies didn't use that table for a timing adder, where the trucks did in that era. Now all the newer stuff appears to use it.

I dont like using the spark advance correction table because its a adder table. So lets say I have the car dialed in perfect at 10 degrees, then I turn on all the sensors for normal driving condition, and it starts to add 5 degrees in areas I didnt want. When I must the main spark tables, Its simply isolating were you want to spark to come from. Sure you can take out spark from the correction table, but I dont like using that table at all and just command to the spark I want. I dont like setting up the tune, and then the computer makes added changes when im done.

I have tried to take some out of the base angle, but didnt find it as effective

Its not wrong or right, it just methodology

Great conversation

HPT has an RTT enhancement, but it's only for Gen3 V8's. Does not require the Roadrunner PCM.

I'd love to see this functionality expanded to the Gen4 motors. I used RTT when tuning LS1's, and it really streamlines the tuning process.

[Tampa Tuning]

But its not for all Gen IIIs just certain operating systems
