Looks pretty good. Made some fueling adjustments to clean up the WOT fueling. Might still take another few revisions to get it dialed in, but it will be really close on this one. I have everything blended out for you on this one, and vtec appears to be happiest at 4500. See how the vtec transition feels on this one, and how it feels in general. But this will be a good view of how the overall tune should feel. We might be able to add a little timing, but 91 will have us limited for sure.

I don't have social media anymore. Trying to reduce my dependency on looking at my phone 1000 times a day...

Here is datalog5. The Vtec transition feels smooth. Can you take a look at the throttle response it feels a little sensitive. Other then that the car is feeling better each drive.

Looks really good, I only needed to make a few fueling adjustments of only a couple percent here and there. We're on the right track for sure. It had one knock right in the most sensitive area, so I removed some ignition there to address that. Other than that it looks great, we're getting close to being dialed.

I changed the pedal map in this one for you to address your sensitivity concerns. I put my base pedal map in this one, see what you think. This pedal map slows the relationship of the pedal to the throttle body some, but still better than the stock lazy map.

Let me know what you think.

Here is datalog6. It feels better it might need just a touch more adjusting for the throttle response. But over all it is feeling better.

Looks good. Made a couple small fueling adjustments to the WOT fueling, very small adjustments. Had some new knock appear so I massaged the timing in those two small areas.

For the the pedal map, I went back to the OEM pedal map up to about 4000 rpm in this next revision, then it ramps up like I had it over 4000rpm. I am assuming the lower rpms are where you don't like the initial ramp in the pedal map.

Let me know what you think. Feel free to drive it however you want from this point on in the datalogs. Just be sure to get at least one WOT pull in third gear and make the datalog at least twenty minutes. But feel free to get after it if you want, it's 99% there so have fun with it.

Definitely getting there. Only needed a couple part throttle fueling adjustments, WOT fueling is pretty much dead on and didn't need any adjustments. Had some new knock creep up in the sensitive areas we have been working on, so I removed some more there. See how this one goes.

Is the pedal map good, or would you like me to put the stock pedal map back in at some point?

Here is datalog8. It is feeling pretty good. We can try the stock pedal map on this next map.I noticed you have the emission sensors off. Can you have them on? Everything is still intact. Let me know what you think of this log.

Looks really good, fueling again is pretty much dead on. Had some knock in the same area we have been tweaking, so I again worked on that some. You don't have any aftermarket engine mounts or anything right, all stock?

Also, sorry about the evap stuff turned off, Hondata has them turned off in some of their basemaps and I missed that. The p0101, 050a/b, and 2279 are turned off for having an intake though. The intakes can cause those to throw codes in some scenarios. If you want them on I can turn them on, but it might throw unnecessary codes for you. Same with the ELD, fuel economy alternator, and rear o2 sensor, I have seen those cause issues as well, which again we can turn on if you want.

Here is the next one for you. We'll see how it looks, I am hoping the knock goes away on this one, we've removed ignition from this area now a few times. I also put the stock pedal map in this one for you.

Yes everything is stock. I’m planning to get rear mount and upper torque mount soon. When you feel that everything is spot on and we are done I would like to have a second map with the sensors on. Other then that keep doing what you’re doing the car is feeling great.

Gotcha. Stiffer mounts and stuff can cause false knock so that’s why I was checking with you. We’ll see how it goes on this one.

No problem on the second map. For now, I turned on the evap stuff for you which should be on. But I can build a second finished one with everything turned on as OEM has it.

Glad you’re happy with it.

Here is datalog9. This one felt really good. No knock count until WOT 3rd gear pull. You can keep the OEM pedal map on.

Looks really good on this one. Made a couple small adjustments on the part throttle, and a couple minor ones on the WOT fueling. It's just about dead on.

Yeah the knock was in the same area, but one small one. I cam going to take a bigger swing at the knock on this one and see how it goes. Then we can check and see how it goes. Otherwise, it looks great, glad it feels strong. I left the OEM pedal map in there for you.
