Hybrid racing on FA5(HELP)
Hybrid racing on FA5(HELP)
Hello forum, a couple days ago installed a hybrid racing cai on my bonestock 8th gen si. Upon doing research i read that running the aem v2 basemap could possibly work on my setup. However, the car was idling horribly bouncing from 2000rpm all the way down to almost 400 rpm. Now, im on another basemap but i am running lean on wot. My idle is alot better(still not perfect but def more stable.) My seperate k24/20 setup is almost complete so i dont really want to get a tune yet if i dont have to. All help is welcome thanks.

Re: Hybrid racing on FA5(HELP)
The AEM V2 basemap won't idle right or drive right because it's a MAF based calibration, you need a MAP based (speed density) calibration for a Hybrid Racing intake.FunkyFa5 wrote: Wed Jan 05, 2022 11:14 pm Hello forum, a couple days ago installed a hybrid racing cai on my bonestock 8th gen si.

The datalog doesn't look too bad, but the fueling is a little off and you have some considerable knock going on. Can you post the calibration you're driving on in this datalog?
Re: Hybrid racing on FA5(HELP)
Ahh did read something about it being a MAF based calibration, and yes of course! sorry forgot to upload the calibration with the log

Re: Hybrid racing on FA5(HELP)
Yeah that new calibration is set to run the MAP sensor for speed density so that is better. However it's just a simple race calibration which Hondata doesn't recommend using anymore. They were a bandaid to some things from back in the day to make it work right. With those, your gas guage isn't accurate and you lose your oil life monitor.
So let me know what you think, I can either clean up the calibration you're running on or we can transition you to my stuff. My stuff would makes things quicker and easier, but it's up to you. I also see you have engine plans coming up, so we can work on getting your current setup really clean so you can have fun until then.

Re: Hybrid racing on FA5(HELP)
Let's try your stuff, just let me know what you need on my end!
Re: Hybrid racing on FA5(HELP)
Okay sounds good. For datalogs, we need them to be 20-30 minutes in length with as much stop and go type driving as possible. Try to avoid steady speed and rpm driving for too long as the stop and go driving populates more data. On the drive, we need one wide open throttle (WOT) pull in third gear from 2500-8600 so we can work on the WOT fueling. For this first drive, keep the driving normal and calm, and also just the one WOT pull in third gear for this first one so we can gather some data before you have too much fun. Once we get some data, you can have a lot more fun in the next revision. I like to get some data before turning you guys loose, just to make sure things look good and we can make any large adjustments before you have too fun.
Take this one for a spin when you can and we will see how it looks.

Re: Hybrid racing on FA5(HELP)
Alright there she is, my motor has 230k miles though(forgot to mention), so on the WOT pull I let off at around 7900 which is where I normally shift when doing pulls

Re: Hybrid racing on FA5(HELP)
It looks really good for a start. I made some simple fuel adjustments for this next one. The few knock we had were all on the shift into 5th gear after the pull so I took some timing out there. We didn't have any knock on WOT or part throttle which is good compared to your last datalog.
I went ahead and set the rev limiter to 8200 for you on this next one based on your statement about shifting at 7900 and your mileage. That way if you miss a shift or something it's closer to 8000 for you. If you want it at a different RPM, just let me know.
Feel free to have some fun with it in this next one if you want. The part throttle fueling looks great, but shoot for 20 minutes again in this next one and at least one WOT pull in third. It's pretty much there, just want to make sure it's solid for you while you wait for your new combo.

Re: Hybrid racing on FA5(HELP)
Appreciate the time and effort man! Tried giving you more to work with on this one.

Re: Hybrid racing on FA5(HELP)
No problem, happy to help! It looks really good man. No knock at all on this one which is great. I went ahead and made a couple of WOT fuel adjustments for this next one. Honestly just nitpicking, it was a percent here and two percent there, just to tighten things up. Take this one for a rip when you can, and on this one, somewhere on the drive, let it idle for a couple minutes while on the drive and it's warm so I can make any idle fuel adjustments as needed. It looks great though, we'll see how it looks in the next one.

Re: Hybrid racing on FA5(HELP)
Alright man, let me know how it did, i let it idle for a few minutes at the end of the log so you can adjust those values if need be. Btw after the last two tunes i feel less torque on the lower end(maybe just a placebo) but it seems run better up top. what do you think man?

Re: Hybrid racing on FA5(HELP)
Looks good again. No knock, part throttle fuel looks great. I did make some idle fuel adjustments based on that datalog, so that's good. The WOT fuel is staying a touch rich, so I took a little more out there, again just nitpicking to ease my OCD. Haha.
Everything should be pretty much the same on low end power. I didn't make any cam angle adjustments, nor was the fuel say super lean to where it made unsafe power in Rev01, if that makes sense. And I haven't made any low end ignition adjustments for knock. I would say maybe placebo, although that sucks too. Being that we're just trying to get you to where you can have fun with it until your K24 goes in, we aren't spending the time to optimize the cam angle map for your setup since you're changing the engine soon. I normally tune each cam angle to get data, then use that data to build a cam angle map. So this tune may not light the streets on fire, but it will at least be safe and hopefully you can have some fun with it. The cam angle map is from a car with similar mods, so it's at least in the ballpark of optimum. With the stock cat in there, it's a little tough to make them really pull a lot over stock. Once you put an RH in there, or of course the engine package you have on standby, they really wake up. I ran Rev01 and Rev02 through Virtual Dyno (VD), granted you have to take everything through VD with a grain of salt, but your Rev01 and Rev02 runs were almost dead on each other. You pulled up a little short on RPM in the first one so peak power is different, but the overlay is almost the exact same.

I made some WOT adjustments for this next one. Take it for a spin when you can. At this point, we're really only working on the WOT fueling. So you can make a ten minute datalog with a clean third gear pull if you want. But if you like doing the twenty minute datalogs that's fine too.

Re: Hybrid racing on FA5(HELP)
I appreciate all the help man! im just glad i can drive it for the following few months knowing its not gonna blow up on me haha. Can you do anything on the idle ? Its 100x better then before just want to to see if theres anything you can do to dial it in just a tad bit more. Sometimes itll fluctuate 50-150ish rpms. Thanks!

Re: Hybrid racing on FA5(HELP)
You're welcome. Yeah it all looks great, and we're knock free again which is good. If you happen to see a random knock here and there in the future, don't sweat it. If you see a bunch pop up, then we would need to address it. But overall it looks great now, and the WOT fuel fell in line nicely with that last calibration. You should be just fine until you get your K24 in there, the only issue would be a failure from mileage, but even that would be rare.
Unfortunately we only have so much control over these things at idle. I made a couple small changes to the fueling at idle, and a small change in the background that might help. I don't see the idle dipping any in the datalog, but if you think it is then it could be. Could also be the tach on the dash being a little off, but again without seeing it in a datalog I can't say for sure. See how the new changes go.
Take it for any length datalog you'd like. Everything looks great, just see how the idle is. If for some reason it gets worse with the new changes we can go back to the last setting, so don't panic.

EFICU-
Would the original FunkyFA5 file be a good place to start for a basemap? Hybrid racing intake only, everything else stock for the time being. Getting ready to start the install this week, maybe tonight. Thanks!
