My S2000 has been through all kinds of issues over the past 6 months: Overheating and oil burning issues, a sleeve that mangaged to settle, a blown headgasket, a freak oil pump failure, and the determination that the oil rings supplied by JE were slightly smaller than the compression rings.

After having the motor pulled out, torn down and rebuilt 3 times over that 6 month span, I think everything is FINALLY fixed and good to go. (knocks on wood)

Today I drove it up to Jacksonville to Mase at Mase Engineering. He's got a great reputation in the Honda/Import tuning community, and has a 1,400hp/1,250tq Ford GT Twin Turbo on his resume.

The dyno chart only tells half the story, as the partial throttle tune is a lot smoother than before!

Mase is a great tuner and person. Thumbs up.

wallet.. hahahaha

 

Very nice result!

How is your RC650 holding up at 13psi? Is it close to maxing out?

 

He said that I had some room left to go.

 

Mase is great. I have been trying to get on his schedule for about 1.5 weeks. I have said that I am open to drive over at his convenience... I was supposed to attend the Dyno Night, but something came up and I could not make it. We were supposed to reschedule at his convenience...

My motor is gonna be getting the final thumbs-up from S&R Performance after the rebuild sometime late next week...

I might be forced to go with CFT to tune it, if Mase does not get back with me...

Sick HONDA - You mind PM'ing me Mase's cell #? He gave it to me a year or so ago, and I lost it. It seems like the internet is hit-and-miss in terms of getting ahold of him...

[QUOTE=jwa4378,Jun 5 2009, 10:17 AM] Mase is great.

 

Am I reading that dyno graph right, you rev'd to 9500?

 

Yup. He responded when he thought I was coming to the dyno night. When I had to delay, I did not get a response as to a date that works for him...

It'll be next week til I get the green light from S&R Performance anyway. I will call his shop once I get her back. Maybe I can hit him up on my way back from Tampa.

My tune is good for driving around. The part throttle fuel map is not as smooth as it should be as well... Just not gonna boost it til I get it tuned again.

awesome, Mase know's his stuff
