Has anyone ever installed a boost controller? I may be getting one soon and would like any information. Im looking at getting a GFB electronic boost controller.

 

From the time I has been with RDX committee
NO boost controller will work on RDX

buy Hondata Flashpro. Save your money

 

X2 hondata reflash is what 349? and it is a tune not just more boost, but a revised fuel map and ignition timing table as well.

 

only HONDATA it sounds like, manual boost controllers don't seem to work on the RDX well..

 

I'm sure a manual controller can work. Any other factory turbo car with electronic solenoids can run them. You just have to use the right lines. I'll play with one once I get flashpro and a boost gauge

 

The ECM will be fighting the EBC soooo.........meh!

 

Has anyone actually tried it?, I've read the "go with hondata" comments, but never seen somebody that did it and failed.

What about setting it to max standard boost only?. I mean, the stock configuration has a boost peak at WOT of around 13psi, then it drops to 7-8psi at high RPM. In some applications (i.e. VW 1.8T vehicles) you can set the boost to a peak of 16 psi and no CEL or oveerboost code will be generated. (on these cars the stock psi behavior is similar to the RDX)

 

iirc church automotive did some testing and came to the conclusion that they don't play well with each other. but to end this call doug at hondata. he can answer the question, not sure if he will but he can.

 

I contacted the hondata guys looking for a reflash for my RDX (ECU with MX code), they did not have it and did not want to try it out. Same applies to the new hondata programmer.

I believe the ECUs are the same since engine and performance levels are the same, I'm almost possitive only the label changes due to thedestination market (I used to work on an automotive compañy that built ECUs)

Being that said, I feel the boost controller is the only way I have to boost it up. I have to wait until my bike get out of the dealer to have a ride and be able to mess with this boost thing.

 

for the price of a decent boost controller you probably could of bought a ecu from an american model in the same year and used that.. i am pretty sure the one sold in mexico is the same as it is here.. the ecu controls the boost electronically if memory serves. so a boost controller will be fighting with it..

 

On newer cars the boost is controlled by a solenoid valve that pulsates as indicated by the ECU. When you use an aftermarket one you hookup the aftermarket boost controller it will take over the boost control function.

Most aftermarket controllers have their own solenoid valve that you will use insted of the stock one. In newer cars you will get a CEL if the stock solenoid is removed, a common way to fool the ECU is to leave the electrical part connected, while the air hoses are connected to the aftermarket solenoid. In this case the ECU still thinks it has control over boost and no CELs are triggered if you don't reach the overboost psi setting in the ECU.

I curently have a couple of boost controllers already, one is a dual stage ball&spring manual type, and the other one is a professional race MHT controller. I was planning to try out the later on the RDX, but need the harley stealership to finish with the upgrades of my bike first.

 

well since you have them hook them up.. see what happens..

 

thats the plan, I'll por the results (I estimate in 2 months or so).

take care,

 

Pretty sure its not going to work out well using a boost controller. The PCM controls boost not only through the wastegate solenoid but also will use the bypass control solenoid and boost control solenoid. So even if you bypass the wastegate solenoid using the boost controler you will have two other systems fighting you. If the pcm sees that the wastegate is not controling boost, it will open up the variable flap on the turbo all the way and open up the bypass valve to lower the psi. If you make it work then awesome

 

Try a search. I remember a guy in NY with a white '11 like ours, JCRDX I think. If I remember right he tried and failed. He soon sold all his mods and sold the RDX.
