I decided to have Bubba at Do-it-Dyno do my tune. I’ve always heard great things about him, plus Church was booked when I had called.
Anyway, the car had been running OKAY since I got the cams in and upped the CR, but I could notice a large flat spot before VTEC. Heh, as you can see by the "baseline" it was more of a canyon then a flat spot. Reason being was that we had VTEC engaging too late, making this problem.
A few things to keep in mind about this dyno though.
Everyone at the shop, even before we ran said it always dynos low. Pretty much every other dyno they have used show 8-10WHP more then theirs. Interesting to say the least. I suppose if its true, and I’m being conservative, then I’m making ~190WHP, which is exactly where I figured I would be.
Also, the "baseline" wasn’t really a "baseline". This was after he took my chip out and programmed what he thought would be good for my set up. So really it’s after he "tuned it by ear" so to speak, then they used the first pull (which they cut short because of that dearth of power there) to see which kinks needed to be ironed out.
As you can see it took 4 more pulls to get it perfect.
One other thing too. I had had the rev limit set to 9200RPMs. The cams for sure make power that high, and my valve train/internals can take it for sure. The limiting factor for that right now is the fact that I’m running the stock B16A2 intake manifold and TB, which weren’t designed to make power past 8200... Even now we have the rev-limit set to 8500 and I’m amazed it climbs that far, but that’s just another thing Ill have to take care of later.
Oh, and you might want to know why there is no torque figure. They broke whatever deal it is they need to hook up the dyno to read the torque on the turdbo GSR they had on before me (286WHP/279tq @ 10PSI and stock B18C1 block after the tune). So no tq. read for me, although I’m sure its somewhere above the 140 wheel mark right now.
It’s good that I have the dyno day set up on the 20th at the dyno I used before the cams and what not. It will offer me a chance to really see how much of an improvement I made with said modifications.
BTW, on a side note... these guys did an AWESOME job. Bubba is THE most knowledgeable car person I have ever met (and I’ve met quite a few really knowledgeable people in this field). The shop looks and feels very professional, and all the people there are very friendly. They even went out and got me Mickey D's while I was waiting for the teg to finish.
We were having problems throwing a CEL after the tune. It was something I had before and couldn’t fix, which was "bad VTEC solenoid" or code 22. This wouldn’t let VTEC engage. We thought it was because I’m using a modified P06 ECU instead of the standard P28 or Hondata and these have problems like that. So he offered to sell me a P28 and hook it up on the spot for 100 bucks.
Bubba went under the dash to remove my ECU, looked at the wiring harness (looks like the pic here but every wire is the same purple color)
He noticed that ONE frigging wire was one space off, and he KNEW it was for the VTEC solenoid! SO he cracked it open, rewired the wire, plugged my ECU back in and it ran like a champ, and POOF! No CEL! On top of that he didn’t charge me any extra for the work and saved me (and cost him) 100 bucks. Above and beyond guys! Total charge? 200 bucks for a good 3 hours of work.
Anyway he said he will tune anything that has fuel management and can fir on his 2wd dyno. If anyone is interested give him a call at 562-424-6162 they are located by Signal Hill in Long Beach, CA.
