Well im in the middle of my lsv turbo build...rods, pistons, sleeved block, the whole niine yards.
Ok heres the question.
If i get a chip from phearble for my Ls civic eg hatch which they say can make about 10-15 more hp with their chip....will that mess anything up if i just put the turbo on my current motor and run an fFMU and missing link for temporary time...before i get done with my built setup.
Pretty much asking if a phearable chip will be worth getting before the turbo and fmu install and if it would still be safe to run on for a couple months?
thanks

 

Just run the stock ecu with the fmu if you plan on dropping a built motor in soon. Then once the built motor is in get some real engine managment, basemap from phearable and drive it somewhere close to get a tune.

 

A 'basemap' as we call it for a turbo Honda is just enough to drive around to your tuner, not to boost on it for a few months. That also assumes they made the chip expressly with the turbo in mind. If its more of an NA chip, it definately wont have any of the boost tables adjusted even close. Even with an FMU, you need to see how rich the FMU is making it. Its not uncommon to see other types of cars even with larger injectors + an FMU.

You can definately use it for a few months, but you'd be an absolute fool to put $2-3K into the motor just to blow it all by skimping on the tuning. You may not split the sleeves, but a bad chip can easily destroy your pistons and bearings.

Use it if you want to ruin your motor.

 

You own a Honda.

You have more aftermarket ECU options than any other manufacturer. Many of which are affordable.

There is NO good reason to go with an FMU. Use the money you would have wasted on an FMU and buy a set of used injectors.

You can have 100% of your turbo gear installed and still not need an FMU if all you need to do is get from A to B until you can afford to do things properly. Just make sure you're not building boost either by watching your gages or taking off a coupler. I drove over 200 miles like this.

I know once i do the built setup then im not skipping on the expenses and am trying to do everything right.
I was just going to see what i can do with just a stock ls that is in the car now. Its been running just fine for about 5 months and just want something different. I have a skunk2 intake mani on it now, and was just going to run the fmu on this stock setup with a turbonetics t3/04. Im not going to skip on the other build hell i already have the hondata for it.
I really just didnt want to spend 500$ on a an ls-turbo when in about 4 months its going to have to be retuned on a completly different boosted ls-vtec. Which is why im just wondering about the FMU.
thanks for the replies

why dont you just use hondata and skip the fmu.

 

He has stated he doesn't want to spend the money getting it tuned twice in 4 months.

 

OK just run the hondata basemap thats what he plans on doing anyways. I would think it would be safer especially if he could throw in a wideband and wire it to hondata.

 

yea Slowb16si that was pretty much what i wanted to reassure myself with. thanks

 

Our ecus/eprom chip basemaps do not support fmus.

Please read over https://honda-tech.com/zerothread?id=1544043 for an introduction into efi tuning.

 

so you think it would be better to have a stock ecu and a fmu instead of hondata which already has base maps for just about every setup?

Dude, a TURBO Chip is completely different from a N/A Chip because the if the turbo chip is made correctly, it will detect boost and increase your injector duty cycle as well as retard your timing accordingly for every pound of boost although it will NOT be 100% accurate because its just a BASEMAP.

Now all the FMU will do is add more gas with boost but what about your timing??? Detonation can DESTROY your motor especially if you are running a turbo. If you send all your details to phearable he can make you a basemap chip (make sure you ecu is ready for the chip) and then you use the basemap to check and see if everything is working correctly until you take it to the tuner which is a MUST if you want the motor to last you more than a few days or weeks.

You can ride around with the basemap chip as long as you stay out of boost and shift before the turbo starts to spool up, I guess.

BTW, John of Phearable makes some good basemap chips to get you to the tuner, that is. I just got one for my Turbo H22A and I only used it to make sure everything works correctly. Car is now parked until I take it to the tuner...

Better be safe than sorry man - just lookin out for ya

 

a friend of mine has been running 8psi with a fmu for over a year and has beat the motor pretty bad many times and its doing fine.

If it wasnt for that i wouldnt ever consider it.
Im not getting it tuned twice in 4 months and i want to be turbo like yesterday so what would be the best option

 

In that case, the basemap chip would be your "best" option over the FMU. Good Luck!

 

good ......thanks
