So over the weekend I attended a free car show with a couple friends at UTI Automotive school near Philadelphia. They were doing free dyno run so I decided why not give it a shot since I haven’t had time to do it. Well let’s just say that was a big mistake. They had no idea how to run it. I had a run of 115hp and 286.7ftlbs. My a/f ratio also read 10.1 the entire time. So needless to say that was a joke but I also wanted to look into the a/f reading even though I just figured out it was a result of those that didn’t actually know what they were doing to run the machine.
So Monday night I went to a local shop to get a proper dyno done. They have a Dyno Pack dyno which connects directly to the hubs without the wheels. I was kind of disappointed at the results to say the least. For those that don’t know the car or don’t remember what is on it, it is Comptech Supercharger, J’s Racing Intake, Comptech Header, RT High Flow Cat, J’s Racing 60rs Exhaust. The numbers I got were 215.9hp and 173.4ftlbs. My air fuel ratio was still not exactly right but I could remember the actual specs of the supercharger and ecu reflash for it for the life of me while at the shop so I didn’t realize the possible issue at hand till I got home. While at the dyno it was appearing like VTEC was not engaging until 5000rpms. I also remembered that I can take the car all the way up to 7600rpms before it redlines when I drive it. I didn’t think the supercharger reflash was set this high and when I got home sure as can be those are the specs of the standard reflash for the TSX. I have never had the standard reflash done before getting the supercharger. I then went to ct-engineering site and looked at the supercharger specs to confirm the redline should be at 7200rpms and the VTEC engagement point should be at 3000rpms.
This is crazy if I ended up with the wrong reflash. I have had the supercharger installed since last august however I have put maybe 2000 miles on it since it has been on at best and never had time to get it dynoed before going back to school. I haven’t had a chance to pull the ecu yet to look at the hondata sticker but I am pretty sure it said supercharger reflash when I received it back or I wouldn’t have put it in the car. Hondata says the only thing I would get for my troubles is a free reflash to the proper reflash and that’s after I pay to ship it to them. I expect my shipping should be covered as well as a possible discount on the kpro because this is ridiculous if it ends up being confirmed.
So I would love some input from people based on my dyno graph compared to TSX536 first dyno graph (hope you don’t mind me using it) which in my opinion clearly can be seen the difference in the VTEC point. So based on the two dyno graphs do you believe I have the incorrect reflash.
Also if it is the incorrect reflash how much damage could I have done to the engine having the wrong fuel maps and engagement points and what not.
