Jester’s Hondata thread

[Integra23]

Also if anybody is planning on buying a upgraded fuel pump let me know. I will offer you a good deal for some data.

I just bought the Hondata HPFP kit with injectors. Still need a turbo..
I also have the Pracworks intake on order.

I can get you taken care of and will even offer you a really good deal if interested. I’m trying to test mods in a step fashion.

Since I want to test progressive mods to see what actually is worth and what is not. I’m doing the same thing with my car.

I helped my friend install his intake manifold over the weekend and we are currently testing but all the mods went in at the same time. So it harder to gauge what affects what.

Also fair warning you have to modify a lot of the lines in the car and the fuel line flops around. A stock intake manifold will work for 99.9% of most people unless you enjoy the bling.

It doesn't have a 10% power increase at 3500 RPM like all the marketing suggests?!

Sucks to hear it's not plug and play especially for the price. I'm used to aftermarket intake manifolds on LS which were easy to swap.

FK8TD has results on his YouTube channel. He's up their in HP but saw a 18% increase I believe. He also estimated what a bolt on gain to be around 7%.
It would be nice to see what gains us little guys can achieve.

There is an increase in power! Especially around the lower end and mid range not too much up top. Since it’s longer runners. It’s fairly plug and play in a sense but lines do have to be modified to fit the brake booster and to connect to the oem spots from the manifold.

The main concern is HP/dollar, you won’t get crazy returns for the money.

Just got done with another FL5, Will have 2 more spots open this next week. I don’t take many cars at a time to be able to provide excellent service.

Last car I did, with XDI pump and 1400 fuel injectors. As you can see the fuel is as dialed as it can be.

Make it in time for your valentine’s date.

I forgot to post this yesterday since this thread is to help also with information and education about the platform.

This is the same car with just slapping on the pump and injectors and enabling the settings on Hondata.
You will be able to see how choppy it is by just going off the settings. Every car needs their own adjustment to bring everything to where it needs to be.

One spot left! Don’t miss out on it. Just had a FK8 owner take the other spot.

So initial testing of the MHI turbo is in progress. Like promised will be doing it in a step fashion to get data on what works and what doesn’t. Initial testing is the car is very happy at 18 psi with the stock fuel pump and injectors. 78-80% duty cycle on the pump.

I cranked it up to 24-25 psi to see how it would deal with it. If it’s hot outside it will edge the pump into the low to mid 90’s with the ocasional blip into the 100% mark at around 6k rpms. Once the temps dropped at night the car was not happy with fuel pump duty maxed out due to the increase in air density. I think on a stock fuel system 20-21psi should be doable without ever maxing the pump but I’m still testing.

Are you able to overlay logs from a stock turbo tune and the turbo upgrade on pump gas on virtual dyno?

Is the MHI turbo upgrade really worth it on stock fuel system?

Thanks for sharing! Does Hondata support updating turbo model data/table(s)?

How much headroom do you have in the stock fuel injectors? If you can share injector duty cycle data that would be helpful.

It will take me a bit to get you the data. It will make power on a stock fuel system especially if you run it leaner to give you more headroom fuel pump wise. So the extra power will be there but the upgraded fuel system is the way to go if you want to take full advantage of it.

I’m on a base map now but once the tune is more refined I will try to get you a virtual dyno of it. I will still test in an actual dyno. To get you a comparison on both. But it takes a lot of time and money to test all of this for you guys so it might take me a bit.

You Now have Compressor and turbine maps to adjust in Hondata along with WG.

@Clark_Kent yes I will post all of the data for you guys. Once I move further along with the tune, just to give you an apples to apples comparison of a finished tune on both.

What I can say for now on the basemap is that at 18-19 psi on the stage 2 it feels just as strong as full tuned stock turbo car running 25psi of boost. With a lot more topend and no drop in boost.

But just as a reference stock turbo I have seen about 280’s to 290’s g/s on MAF readings depending on mods. On this turbo I’m already past the 305’s g/s. Injectors are hovering at around 30% duty and on these cars the max is 50% since its Direct injection.

But I promised myself that the car will progress as the business progresses. 100% of the funds from tuning will be put into the car since it takes a lot of effort and money to get you guys the best data. My work money goes to the other priorities.

 

[Jester04]

Got out of work early and updated the map. The car is breathing much better than the stock turbo. Still dialing in the aircharge to where I want it for the stock fuel system to get you guys an idea od where you would be at.

One of the findings is that you can run pretty much 24psi on the stage 2 on stock fuel system without a problem. But it would require a leaner AFR to keep everything happy. If it’s a street car it can run leaner with 0 issues. If it’s a track car I tend to go with richer air fuels so the boost would have to be lower. The car no longer feels like it falls flat on its face after 5k rpms.

Also all this applies to ambient temps in the 70’s and 80’s. The colder it gets the more fuel you will require. If you live in a colder climate boost levels will have to be lower. So as far as this goes you can run a MHI turbo on the stock fuel system but you will leave a lot on the table if running richer AFR’s. So the upgraded fuel system would absolutely be needed to utilize the setup efficiently.
