K24a2 swap in 8th gen

[EFICU]

Yeah I see you're using a basemap that is MAF based. It would be better to tune it speed density for the intake and your overall parts package. With most intakes it's hard to verify the accuracy of the reading coming from the MAF sensor.

Couple questions on your original calibration:

-Are you having any overheating issues? The way you have the fan on/off temperatures are counteracting each other. You can't have the fan on temp at a lower temperature than the fan off. In the calibration posted you have the on temp on at 180 and off at 195.

-The vtec rpms are 5800 lower and 6500 upper, did you move them up for any certain reason, or just for tuning purposes?

No I don't use TeamViewer currently. Tuning them properly is roughly a 4-5 hour process so using TeamViewer is rarely needed.

Yea I messed up on fan thing I guess an I did set the vtec up Like that

[Rocko08]

And no over heating issues I just put the Temps in there wrong shoulda been on 180 off at 165 ,or something

[EFICU]

Gotcha, if you're running the stock thermostat, it should open at roughly 172*, so no need to have the fan off temp lower than that. Most likely the fan will never shut off with it set to 165*. On these Hondas there really isn't a need to run the fan off/on temps that low, they're designed to run a little warmer. But it's entirely up to you, I'm guessing maybe you guys run diesels on the cooler side?

On vtec, make sure you don't set the upper limit any higher than 6500. You can run into valvetrain issues at that rpm or higher if it doesn't engage the high cam.

Anyways, as we discussed a few posts back the proper way to tune it will take 10-12 revisions. If you're doing all your tuning on someone else's laptop that makes things difficult for you but manageable to make and send datalogs. If you only want to clean up the file you're running on, we would want to at least convert it to a hybrid calibration and reduce the cam rotation from 50* down to 40* or so to be safe. There can be piston to valve clearance issues above 45* of rotation depending on which year your engine is. That and it probably doesn't make more power above 40* of rotation anyways.

Let me know how you want to tackle it and we'll go from there.

Its a 07 k24a2 ..I just wanna dial it in the easiest way ..I don't gave a laptop of my own rn I have everything on the one at work .we can probably do it tomo evening or one day this week in the evening..you say it will take a couple hrs just let me know when an we'll b ready ..im not worried about gas mileage I want it to run as hard as possible with out tearing anything up is all..

[EFICU]

Okay sounds good, yeah I think the 07 has a little more valve clearance than previous years. I haven't had one apart, so I'm at the mercy of the internet forums, you know how that goes. It's most likely going to run out of breath around 40* anyways, so I don't think we'll have to crank it up near 50* where the issue is most likely to rear it's head. The K24 has a little different efficiency scale compared to an 8th gen K20.

Yeah it would be best to transition you to my stuff, that way everything is set and we can hit the ground running basically. Tuning all cam angles properly is the only way to get the most out of them. We use those fuel tables similar to how a dyno would read, as you know in diesel, more air and fuel means more power, so we need those tables all tuned to get the data. Not to mention it's better overall product, I don't like doing one size fits all tunes.

So give me as much of a heads up as you can for when you want to tune it. If you want to try to bust it out in one shot we would need to make sure we're on the same page, as each datalog will be twenty minutes of driving on your part and then posting the datalogs. So even best case scenario is three hours. Or if you want to space it out over a couple days after work to use the laptop that's fine too.

When u want to send tune and try it I can get it in there and try it out and see what it does
And log it send it back to u

Okay, if you're unable to commit to the process of tuning it, we can just try to clean up the file you're driving on. To tune it properly is a process as we've discussed, if you're wanting to get it done in as few revisions as possible it's probably best to clean up your file so the fuel is good and minimal to no knock. I'll just pull some timing where you have knock and clean up the WOT fuel in a couple revisions. But to tailor it for your exact car it needs to go through all cam angles to gather data for vtec and cam angle mapping. If you want me to guess at all that stuff using one of my files to start I can try.

I guess basically tell me how many revisions and datalogs you think you have time for or are willing to make, and I will try to fit the best product into that box as I can.

[Rocko08]

My bad I'm trying to get free we was kinda slow yesterday but u can send me a file I'll log it an send it back or whatever u want me too do I appreciate it .were usually swamped here at work but I'm ready to do whatever to get started

[Rocko08]

I can do as many logs an revisions as it takes it just might take a few days

[EFICU]

Okay, sounds good. The first calibration I would attach, we would want to get a datalog ASAP on that one so I can clean up any big chunks right away if there are any. Then from there you can go a few days because I can better design the next cam angle map once I get the 0* angle tuned.

The only real questions I have, is there anything in your original calibration you want to keep? I see the rev limiter at 8200, you're comfortable with that because of the oil pump? But let me know if there is anything else you want to carry over from your old tune and then I will get the first calibration posted for you.

[Rocko08]

Okay sounds good u can set everything at what u think is best I think the vtec would b better at like 5000 ..an rev limit at 8k ..i have the car an stuff here at work so I could put it in log an stuff .thanks

[EFICU]

Okay here is the first one for you. Vtec will usually be determined based on what the fuel tables look like, but at the end we can discuss where it looks best and where you would like it to be. Ultimately we can put it wherever you want it, it's your car, but we'll see what the data shows and then discuss it. The goal is a nice linear power increase at vtec, if it's too high or too low they can have a power fall off before or after vtec. I will also be moving vtec around in a few revisions, we want to tune the RPM window as well as finding the vtec point, so in a few revisions I will move it up and down from 4000-5500 to work on that. For now, this revision has it as 4500 to get us going and through the first few cam angles efficiently.

So for datalogs, shoot for twenty minutes in length with as much stop and go type city driving as you can. On the drive, make one wide open throttle (WOT) pull in third gear from 2500-8000. For the first datalog, only do one WOT pull in third and keep the driving normal while we capture this first bit of data. This is the 0* cam angle, it's not the most powerful so don't get discouraged if it doesn't strong. The 0* cam angle lays the foundation for moving up in cam angle. As we move up in cam angle it will get stronger and stronger.

Take this one for a spin when you can, and let me know if you have any questions.

Ok ill get that one in an log at asap..

[EFICU]

Sounds good. We'll see how it looks.
