it's this sat marc...see first post...i'd like to get my msm on the dyno..(scratch)..can't do this sat thoughDepending on a date I can go. I actually need to dyno my car after I get my new exhaust.so I guess put me as tentative.
Well guys just got back from the dyno and EH not really impressed. Yes the overall drive of the car is a lot better but the numbers are,, You decide,
HT Tune( CP-E Nano) WHP 284@5300 and WTQ 291@4800, I really thought I would have hit over 300.
Stock was WHP 273@5500 and WTQ 284@4600..
So I only picked up 11 WHP and 7 WTQ with the HT..Not what I was expecting at all.
The Tuner said the HT A/F was unsafe being that rich at 5200 its in the 9's, The stock tunes A/F looked a little better staying in the 11's 5600. Either way he told me the car would have broken well into the 300's if the A/F was not so "pig rich.
But maybe the HT only shines on a stock car. The other car with me made on HT( MSP CAI Tune) 271 WHP and 299 WTQ!! And shock his numbers where down to 236WHP and 259 WTQ.
Special thanx to all the guys at Boston Dyno and Tony

New guy here. My name is Luis and I read this forum, but I don't post much. Just want to say hello to everyone.
My car is the other car that made it to the dyno on Saturday with anm6's car. My motor is stock other than the Mazdaspeed CAI, Cobb intake and the HT flash.
Basically I picked up 1 horsepower at the top end vs. the stock tune, however I did better in the midrange, see below and attached dyno files.
Overall:
Horsepower: 271 vs. 270 a gain of 1 HP
Torque: 297 vs. 273 a gain of 24
At 4200 RPM's:
Horsepower: 238 vs. 207 a gain of 31
Torque: 297 vs. 258 a gain of 39
In addition to what the tuner told anm6 about the fuel dump, he also told me that with the HT tune my car is dumping so much gas that it misfired/dropped spark. It shows up on the attached dyno sheets at around 5800 RPM's. He also said the best thing would be for HT to do a new tune as another option that runs leaner up top and keeps the AFR's consistent around 11.25, instead of dumping gas and going much lower.
I also attached a dashhawk log from last week on the street not at the dyno. It show the AFR's going to 10 and a little lower. Boost to 19 one time. Fast run not much logging time. Please let me know if things don't look right.
I'm glad I dyno the car, it was interesting and I'm leaning about tuning. I like having the HT, it's just I wished it was perfect. Maybe no tune is perfect.

Hypertech is you guys's biggest problem, and its the reason your not seeing any "really good" numbers, on top of that the tuner doesnt know crap because if you were running AFR's in the 9's theres alot of he couldve done to lean that out and get you better numbers.. but im not going to go on about that. /rant
get the Cobb AP Tuner/ CP-E Standback and come see me

Kinda tuff to take fuel out when the tuning device you has it a OTS flash.
The HT is NOT tunable just a flash unlike the Cobb AP, So how could the tuner taking fuel out???

Exactly
The AP has the ability to do it on the fly now and you dont need the ap in the car anymore, you can run the software from a laptop while your sitting in the car changing things around and then reflash your map with the laptop and do another run. In all fairness everyone who has a HT and then runs their car on a dyno has seen low numbers, and pig rich AFR's.
I mean i could street tune you guys on the AP and get you better numbers then that.
