my tuner here in lincoln said he has had trouble tuning it but i have a greddy spec2 boost controller will that seloniod work also with hondata? it is a normally closed valve also

 

Your grammer needs some work dude lol...Hondata sells one or you can use the gm for boost by gear...They are not that hard..Only 2 wires

 

i think he meant programming it but should i be able to use that one if needed?
i now the gredyy boost controller is good but is gear boost that much better

 

tired man and yupp handata lol its new programing software its all about touch and feel lol

 

boost by gear is a lot better! i would go with the hondata boost by gear with the mac solenoid!

 

what is the mac seloniod? will the greddy one work?

 

I was in the middle of setting up my Hondata boost by gear with the GReddy solenoid. I couldn't get it to work right before I literally blew up my turbocharger from it spiking to over 35psi one too many times. :\

Soon as my new turbo gets here I am going to continue trying with the GReddy solenoid. My turbo arrives tmrw.

 

boost by gear is the best thing since sliced bread in my opinion, it makes totally useless 400whp street car hook like it has 200whp in lower gears and you can't really ask for anything better then that. do it and you won't regret it.

 

A MAC solenoid (PN: 35A-AAA-DDBA-1BA) can be had for under $30 shipped new. It is a great value for the features Hondata PWM can offer.

My advice would be to sell the Greddy boost controller, buy the MAC solenoid, and make a profit.

IF the 1 or 2 authorized distributors in your state have one on hand. Otherwise it's a 2-4 weeks wait. MAC does not allow their distributors to ship across state lines. But FYI as long as a solenoid valve is 10-16 volts, 3-way (or plugged 4-way), and flows above "0.05cv", it will work with Hondata's boost control. I prefer normally closed, since a power loss or solenoid coil failure will result in low boost. Normally open "fails" to 100% duty cycle...

I thought Handata was a new portable version... Your tuner sounds like he's the monkey see monkey do type. It's easy as hell to "program" it. In the link below it's all explained. The bulk of your work will be finding the PWM settings. Manually set it at duty cycle increments and log what boost they give in each gear. Then plug them into "Pressure vs Duty Cycle". If your boost "hunts" in certain gears, you should do a manual duty pull in that gear to find the new ideal duty cycle. 30% will be a bit different in 1st vs 3rd gear sometimes.

BTW look at the high/low boost switch section. You can put the switch anywhere (hide it) vs some stupid "scramble" or 2nd setting on an external boost controller.

 

my guy is a hondata authorized seller dyno dan here in lincoln or anywhere close that will do it better that is close since he wants 450 to 500 to tune it

 

You need to make pulls with the boost controller hooked up and set as fixed duty cycle doing small incruments at a time going up and log the boost you get with what duty cycle. Then you need to input that data you got into the pressure vs. duty cycle table. after that is done you can input what pressures you want in what gear and rpm. and pay attention to what you get for boost. also with temp changes it will require you to add and or subtract boost in the air temp compensation table at the bottom. hope this helps

 

Your tuner should set it all up for you if not then you need to find another tuner.

 

his tuner said he has had trouble with it so yeah another tuner. its pretty straight forward

 

its dynosport here in lincoln he is the only licenced dyno in the state of nebraska i thionk i will go talk to him and see what he says about tuning the gear boost

 

What does a licensed dyno mean? Licensed Hondata dealer?

I've used pretty much every OBD1 ROM editor, and the only difference is understanding menu layout and functions. Tuning is tuning. If your tuner cannot tune PWM boost-by-gear, find someone who can. Anyone experienced with eCtune/Neptune PWM boost-by-gear can tune Hondata boost-by-gear.

 

yes he is a handata dealer and a nascar licenced dyno shop his website is www.dynosport.com he has a buncha cars on there he has done

 

the handata is very easy to use.


just tune first with fixed DC, setup the table with its corresponding psi.
and off you go!!!

get the MAC solendoid.

xenocron has stock of that. its cheap too. 100% NC.

 

ok cool so basiclly i just need him to wiree my ecu for it and then he can set the boost off the base line. question tho how does the car know what gear its in?

 

it computes the vss and rpm...
that's why there is a setting there for you gear ratio/fd.

so if your vss is not working it wont work.

 

Make sure that the ECU has been modified to operate the boost control solenoid. It'll never work if the PWM output for the EGR Valve hasn't been modified.

Just like everyone else said, set up is pretty easy.
Make a pull at a few different duty cycles to see what boost pressure that equates to, then build the table.

 

ok and mine hasnt yet but seems easy enough to convert
