Dyno Tuning

Well, I had a thread in here with information on dyno tuning for 86-92 third gens in conjunction with some 4th gens. Unfortunately, a mod moved it here to the northeastern section. I had it in here because I don't see any third gen guys posting in the northeastern section, and wanted to get some exposure out for it.

Mods, if you could not delete this thread or maybe move that link back here I'd appreciate it.

Bump, we're less than a month out. Still plenty of room.

Paying somebody that much money to adjust a WOT fuel curve is rediculous. Why? Because how hard is it to adjust fuel vs. RPMs when you have a Wideband on a dyno? ITS NOT. ITS EASY.



See that curve? Easy. Paying somebody that much money to tune your WOT is ludicrous. Furthermore, any tuner knows that you should tackle your part throttle before WOT. Don't tell me that I don't know what I am talking about either. I have been doing this way too long.

Well, I don't know where your getting these assumptions from, but how about a retort??

Who said that this is just going to be a WOT A/F tune?? No one.

Furthermore, look at the going rate for a dyno tune anywhere. You're talking $400+ easy including dyno time, so this is by no means a ridiculous amount of money.

Lastly, please try to refrain from coming into a post and bashing the purpose instead of adding something constructive. It serves no purpose and makes you look like an ****.

I am a total **** for showing people the light. You can do this yourself for cheap ... and you can have the ability to change it yourself in the future for free. It is a WOT dyno tune. Nobody is going to sit on the dyno doing part throttle driving for 1+ hours to tune MAF tables or VE curves ... and nobody can tune those WITHOUT having significant time at part throttle. If someone is 'supposedly' tuning your part throttle then they better be in your car for 1+ hours at part throttle collecting data and making changes. 1+ hours is unrealistic too. You still have to do the spark, acceleration enrichment, etc.

Ok, most people don't have the knowledge, the know-how, or the equipment to properly tune a vehicle.

The guy doing the tuning has been doing so for quite a while, and KNOWS what he's doing. Just because it may take you an hour to do a part throttle tune doesn't mean it's going to take someone else that long.

For some people it's worth paying a little bit of money to have their car tuned on a dyno, for KNOWING where they stand when it's over, instead of guessing.

Also please remember that the tuner specializes in tuning 86-93 GM chipped vehicles, has an extensive database, and is pretty well known.

All I ask is that if you're not going to constructively add to the post, to please let people make up thier minds instead of trying to sway them to not do it. If they want to have a dyno tune, they'll contact me, and if not, they won't. Plain and simple.

I wasn't calling you an **** by the way, I was making a correlation to the fact that 9 out of 10 times when someone jumps in a post with bashing on the intent, it makes them look like that.

*Edit* I just realized who you are. I LOVE that video of your car. My black 93 is getting a cam from the same guy who did yours, I can't wait.

This is absolutely, without a doubt, wrong. I mean no disrespect. But this comment is 500% wrong. I've been doing this way too long. MAF systems don't take much tuning on a moderate setup. But, a SD system cannot be done in less than an hour where you are hitting most of the points on both VE curves ... and that is even WITH using VE Master which tunes the points for you.

I'm not here to say that PCMForLess is bad. I am not saying that at all. I'm sure he can get a great tune if given enough time. I am just saying what I have said in order to influence *some* people to begin thinking in a different light. If I get one person to try it themselves then it is a success. The stuff I have done with my tune is absolutely amazing ... and you guys can learn how to do it too. If you have a really good understanding of how a 4 cycle engine works and you like computers and have possibly assembled your own at home then you CAN do your own chips.

You'll be very happy with Joe's cam. It's a beast. Be careful with your 93 which is speed density. It can take a lot of tuning to get it right. But, by 'right' I mean perfect. If you drove in my car it is smooooooooth and idles awesomely. But, I also changed how the ECM is using the O2 sensor readings at idle. That's a big deal with Speed Density and Joe's cams ... getting the idle fueling to work really really really good. However, most people just tune the fueling and call it a day. For a really good tune on a Lethal EFI cam you'll also want to tune other stuff like BLM MAP and RPM boundaries, the Idle Cell marker, O2 constants, etc. It will work Ok doing it the standard way (i.e. just fuel) but when you do everything it is a very nice difference.

Alvin and I are going to be getting what we can done on the dyno, and then he and I are going to back and forth over email with datamaster logs for finishing and polishing up the tune for any "rough spots."

I thought you were just going off about the price for the dyno tuning. If you are just trying to put a different point of view that's cool, we just weren't on the same page.

If you're close enough, feel free to come and watch on the 14th.

However, in order to get to tune your own car, you'd have to put extensive hours into learning it while someone has done it many times already with a huge database of settings and experience. Not to mention the equipment you have to purchase. All of which is for a one time use every few years. Once the chip is setup right, how often do you need to tune it? Only when you have setup major mods. This is just like gear changes. I have the theory and could buy the tools but for the number of times I had to do a gear change (2 in the last 13 years) why do I want to own that equipment and bother with it? Now if the tools were used for other things like my sockets sets for example, I'd buy it in a heartbeat and DIY. Also if it took a professional 1 hour to do something, it might take me 4 or 5 because I don't have the same experience. If I was running a racing setup where I did this tuning on a daily basis, I surely would buy the parts and learn to do it but in this case, I don't see the economy in it.
