Oh, maybe thats why its a stock cal file...

HPTuners is MUCH better than TC for LS based trucks. TC is a useless program. Good to change tire sizes and to play around. Bad to actually tune properly.

I've been tuning LS based cars and trucks with HPTuners and other software (to learn), lately. This is why I am pissed at Monodax and TC. Our software sucks and we have no support. We NEED MXSCAN.

I'm going to beat the MXSCAN drum in every thread until James rears his god damn head. Or until TC gets in here. This is bullshit.

HP Tuners has no support for Real time tuning and if they did, could you afford it?

Unlimited RTLS1 Software hear in Aus sells for about $12.000 AUD.
Sounds like a good product by the way. Logs data at much higher frame rates.

Have you explored all your options. I have 5 different scantools which are PC based, they all have there place and worth with me. When MxScan is released I will have a copy of it to. Do you own a wide band controler to monitor and Log your A/F ration? Sounds like you have, or use a shop dyno, so whats up with using another scan tool for now?

I've had no drama knocking out Big Hp tunes with TC. I do understand you and others have issues with your rev limit, and such. I think being humble will get you much further. It works for me.

Many Thanks to John and Craig.

Kind Regards

Where is TunerCats support for Real Time OBD II tuning for GM PCM's? I see no real time tuning option available. Maybe for OBD I you have real time using an emulator, but thats totally separate.

I could use another OBD II Scanner, this is not the problem. Many work and work well! The problem is integrating it with TC and not having to make so much guesswork. MXScan was supposed to help with this. As it stands now, I can tune my truck with HPTuners in maybe 8-10 hours and have 700whp fully functional and make minor changes as time goes on (acceptable). As it stands now, I will have to tune at LEAST 50 hours just to make this thing run like I want and make the 700whp. It is very difficult reading logs, interpreting cells, trying to get the same cells over again after you make a change, etc. etc. Try it sometime! I am!

I'll leave what I can afford up to your imagination. Just know I wouldn't be here banging a drum for something I could not afford. We could both pull out our dicks and compare length, or we could break out pocketbooks and compare balances. Neither means a shit. FWIW, I have a big dick...does it matter?...no.

A/F ratio is not everything. I can dial in my A/F at WOT, but that doesn't do crap. I may drive WOT stoplight to stoplight (my driving record proves it), but if I give my mother the truck to drive for a day (it happens), I would like her to be able to comfortably drive it, even with 700+ at the wheels. My mother is 5' about 95 lbs. soaking wet. Her throttle inputs are so minute, that her 1989 Buick LeSabre gets 23 miles to the gallon (I tuned it up perfectly, 150k miles). I am the second owner (bought at 80k) and I meticulously maintain the vehicle. Nobody believes it gets 23mpg but we tested and verified many a time! When I drive it, the car gets 17-18mpg when I drive it easy, and 15-16ish beating on it. Trust me, I know the car runs awesome when mom drives it! I doubt she has EVER taken the motor over 3250 RPM and thats a fact! I wind the motor out every once in awhile.

So, I really need my tune to be perfect spot on. I want to be able to cruise down the block at 10 miles an hour and people think it idles and runes like a stock truck. Then I will hammer the throttle and "thats all folks".

I'm sorely dissapointed in MXScan. Everytime I add another modification, I need it that much more desperately. It would save me a lot of time if it was integrated into the TC software.

Tuning is done on the street via Wideband O2 sensors AND EGT sensors. The ONLY way to tune. I _NEVER_ "tune" on a dyno anymore. Learned this the fun way. People run leaded gas on the dynos and ruin the O2 sensors. I bring my own. Secondly, dyno loads do not equal street loads, and street airflow. What works on a dyno, never works on the street (exaggeration, but trust me, airflow matters). I had a problem where on a dyno the car ran perfect but on the street it would magically stall all the time. The car stalled at 145mph! No power steering or brakes at 145mph! Talk about scary for the driver! Luckily it is a 6spd and he restarted it with the clutch.

What happened was after a big pull, when letting off the throttle, the MAF sensor got reversion or some type of disturbance of airflow and caused the car to go lean or rich (I forgot which). A simple rerouting of the intake pipe and some carefully placed shields solved this problem. This problem never happened on the dyno. If the driver was a moron, this car would be totalled and he might be dead.

Maybe you can knock out big HP tunes with TC because of your experience. I may try hard, but I am an amateur. Eventually, I'd like to be a tuning guru (not for profit, for my own expertise). I've been learning AEM and other stuff lately.

I've been patient and humble waiting for MXScan. A year later, and countless promises later, still nothing, not even the developer answering questions. I have every right to be pissed.

Stealth97,

Yes, you do have the right to be pissed. But I would preferr you keep your old fella in your pants thanks. My wife and bank manager are quite happy, I will leave that alone...

You bring up many issues, some of which I have confronted aswell. intergrating another scantool to function with TC's tuner for now was one of them.

Converting engineering units to VE% was something that I had a look at and this is where I'am at. Over all, yes, I have had to improvise for now, and other software's are further advanced. check out the attached excell doc, you might find it interesting. Bye the way, it's not public, so it's non functional. I guess the whole idea of DIY-EFI is to learn and improvise, do the best you can with the ability and tools you have.

I have a number of different softwares for tuning, so I guess I 'am not in the habbit of hanging crap on developers. The one thing that attracted me to TC's software was that it was unlimited use of vehicles for the initial cost. Understanding that software updates are free I know in time, so to speak, it will further advance. For me to have the same unlimited access to the vehicles I choose in other softwares, the cost would exceed $12.000 Aud. TC just suits me as I'am no tuning shop with high turn over.

Sorry to see that your fuse has run out, sometimes that's life.

The feed back from Craig looks good for all, I would'nt like to see you sell up, move on and be further disappointed!

Lets get on with the show..............?
