Overall it looks good still. If you know the gear ratios we can use them to adjust the speedo if you want. If it's no big deal then don't worry about it. Once you get it all broken in let me know and well go over it all some more.

I went 4.76 to 4.37 I think.

Gotcha. Test the speedo on this one and see how it is.

I think you adjusted it backwards? I was going way faster than my speedometer was saying.

I changed it to what you stated, from 4.67 to 4.37. Go back to Rev55 and we’ll worry about it another time.

I just changed it back and went for a drive. I was able to get a steady reading at 80 mph (on google maps) and the speedo reads 76 mph. It feels so much better while cruising down the freeway.

Sounds good. Keep me in the loop when you get it all broken in.

I finally got it broken in and it feels great. It also looks like I gained 4 to 6 mpg on a combined freeway, traffic, and up to the entrance of the Rubicon trail (loon lake). I'm going to do an oil change on the trans and maybe go to Wednesday night drags if it's open.
I did go into the tune and changed the gears and got rid of the 3% we had for the tires. Now it is only reading 1 mph under. I will recheck it after I get new front tires.
That's strange, it's not downloading my datalog and then showing my hondata is unlocked. If I unplug it and replug it in, it goes back to locked.
Also, do you have any idea on how to get back my hondata app on my phone? Broke my phone a while back and I can't get it back on my new one.

Sounds good you got it all worked out. Sometimes I think you have to unplug cables from the FlashPro and plug them back in to get it to read. Seems like I remember having that issue once or twice, trying to get it to read locked. Interesting the app won't show up though. If you have an iPhone, I would think it would download all the apps. Unless you were using the old Hondata app, if that's the case you can't download it. You will need the new app.

I ended up just buying the app again. All the car needs is an alignment and she's track ready. Got a pair of Yokohama Advan Apex tires on the front and the new Teins shocks are really helping the tire bite in a straight line. Took a 4500 rpm launch really good for the street (in log and first real launch). Instinctively I am still babying my 1-2 shift. I have already changed the fluid in the trans, so it's ready, too.

Hope you're having a good 4th.
I finally got the O2 extenders and moved the O2 back to the second hole I added 4" back. I always thought it was too close to the merge and at higher rpm it couldn't read very good. I will also clean the air filter and see if that changes anything more.

Hope everything is good with you. I see you haven't been here for a while, but I will throw it up anyway. Ignore the last datalog, I had 2 coil packs not screwed down and I had a dirty air filter.
