Gen 5 Camaro Tuning, Diagnostics, Dyno results.I've set a few gen v swaps up, and even from car to car with the same basic modifications.they have tended to like slightly different fueling strategies. Also the "same" combo can react very differently in different vehicles. There is a lot of material out there you can read, but a lot of it is also just plain incorrect or wrong. In which case it'll do rolling burnouts at 70.

But that car is now an 850hp Bob Costascat around town, cruising down the highway, etc. Makes a HUGE difference in the usability of the car. I spent about 10 hours doing not just WOT stuff but a ton of drivability and part throttle stuff, as well as setting up the electronic trans, lock up points in the converter, shift pressures, etc. I just did a blown big block with a procharger and a holley fuel injection system.

Stuff all takes a large amount of time that most people in general don't want to pay for. On/off throttle transitions, part throttle cruising under various loads, etc. They nail the WOT stuff, but thats the easy part. No tuning needed other than disabling VATS, recalibrating the speedo, maybe fix the MAF transfer curve if you are not using the original air inlet and airbox.ĭrivability is what most canned tunes and even a lot of " so called" dyno shops miss the mark on. LS swaps are really easy because GM made the computers kind of self contained, and so you just use that. Got a set of injectors from a (blank)? Copy its injector tables. HPT used to have a really good tune repository. The rest is all lofty stuff like intake manifold wall wetting that doesn't change, or really esoteric fuel injector characterization that is easiest dealt with by using OE injectors (aftermarket are 90% junk) and copying the tables from whatever those injectors came with. Your main focus is on VE, MAF, and idle flow characteristics. Really, 99% is stuff you should not be touching. Good tuners write their own logging parameters and math channels to do the dirty work. Some of them are pretty basic, like take a histogram of X behavior and multiply a table by the difference, table smoothing, etc.

Tools already exist to get a good tune with HPT. And I have no doubt chatbots are good at claiming a terrible tune is great since they have no concept of reality underlying the data.īut without good data, either from your engine or a massive library of good dyno tunes, AI won't be much help.Īre you talking aftermarket computers or OE computers? HPT tunes OE computers.

I could also see the scammers making bogus tuning devices (originally resistors inline with the IAT sensor, more recently LEDs that plug into the OBD2 port) claiming they're doing this, if they aren't already. I could see a dyno shop with a huge library of dyno tunes making approximate tunes to order by averaging or blending tubes, but this would just be an automated way of doing what experienced tuners may do manually to make a starting point for a tune. You only see it on OE application and some very high end pro racing events. But that type of analysis requires more dyno time than conventional tuning, not less. Many OE ECUs these days are what are called model based, where they collect a massive amount of dyno testing data and have a computer fit a set of equations to their data. And they're no better than the statistics you give them. Most of what we call AI, including large language models, are statistical analysis tools.
