That would be great... I would love to have a module that would give me a second throttle that constantly holds equal angle to the first throttle. I would start machining the intake for it right away... i dont know how popular of a product it would be, but cool nonetheless.

 

Interesting. Anyone have SFR's twin intake/twin MAF set-up to compare with your prototype?

 

Interesting project.

Are you considering two original OEM sized DE throttle bodies (because you're FI) or two of the standard HR (smaller) dual throttle bodies?

 

This would be an awesome upgrade!!! Subscribed for uniqueness!!!

 

JB,

was something of going with 2 DE TBs.

 

The MAFs are easy to wire up.The throttlebodies are not.We had a special driver to drive the throttlebody made for us. It works very well.We can sell you one of these drivers if you need.

Kevin at KP.....I have contacted you numerous times about buying some of your products and was going to see if you guys could build the driver box for us but you never returned any pms and basically have disreagarded me.Probably not a great business practice IMHO.

 

Tim,

My appologies if I haven't responded. I don't, off the top of my head, ever remember getting any messages from you. Please contact me again if there is anything you would like to discuss or if you think we could help you out in any way.

 

tim, I don't know what to say about that. I have approached Kevin about a variety of different one-off projects over the last couple of years. He has always been very interested about getting involved. I even had some odd issues on a module of his that I was beta testing. Even though, he has since decided not to go forward with that particular module, he has continued to try new things to get this module to work for me.

Back to the original topic though. Thanks for chiming in on this thread! You are the only one I am aware of that has completed the dual TB conversion. Does your module use feedback from the second TB or is it just a slave to whatever the 1st TB is doing?

It slaves off of the master TB so it is synced up perfectly withthe master.We originally ran right off of the motor of the master to the slave and it worked great for about six months and then ti fried the TB driver in my ECU.On other cars though,it did not work at all by just running the slave off of the masters motor.Very wierd. So we determined that it would be best to just build a driver independant of the master but still synced to the master.Like I said works very well.

I sent you a pm regarding beta testing your flat foot module.No response.
I sent you a pm about buying the flat foot module. No response.
I sent you a pm about building the TB driver box. No response.

After three pms with no response,I figured you didnt want to do business together.

 

Tim,

I checked through my PMs and on 6/16 I did reply to your request about the two step module with a request that you Email Kris for more information. Did you ever Email him?

I couldn't find any PMs about the throttle body, I'm not sure how long ago that was.

Again I appologize if I haven't responded to you!

About the driver board you use, is that something you guys build in house or something you had made by someone else? We could develop a "piggyback" controller like the one you are talking about and incorporate the TPS signal in to it (not sure if that is value added or not as it would be fairly obvious if the TB failed).

 

Hi Kevin,

I just sent you a PM related to another issue. If you do not get it, please let me know ASAP.

Best regards,

T

I think I did email him.No problem though.I am glad we got that out of the way.I just thought you didnt want to deal with us.But I will be in contact with you in the future.

We are having someone else build the box for us at this time since we dont have that sort of capability.

 

[QUOTE=TurboTim;6579307]Is the twin T-body board a separate stand-alone module?
Can it be interfaced (not sure how) with either a piggy-back ECU or a stand-alone EMS?
In your experience, which ECU/EMS interfaces best (i.e. without hic-ups)?

Side note: Are you developing a twin turbo kit for the 370Z?

 

What ECU do you use? How exactly do you wire them up? Are you using OEM VQ35DE MAFs or something else?

 

The TB driver box is running off of the stock ecu.PM me and maybe we can work out a deal to buy your box and I could give you some secrets on how our box works.The box will work regardless of what EMS you are using.

I am using an SS box to control fuel and timing on my car.I am using the OEM mafs.They are wired together except we left the IAT wire disconnected from the slave.With the two MAFS combined,it reads half of what it normally does on each bank which totals the same voltage as a single MAF. No fancy electronics required.We also found that we can disconnect one TB altogether and the car will run just fine.Perfect is case of a failure. Just dont boost it or that one bank that is disconnected runs extremely rich under boost

We also noticed the stumbling through idle syndrome that plagues alot of people has been eliminated.We have incredible throttle response with the two TB's and you can also raise your idle speed easily by adjusting the set screw on the slave throttlebody.There were alot of benefits from going to a set-up like this.Oh and it looks super trick too

Anhy of them since it is still relying on the factory ECU toi control the TB.




Are you developing a twin turbo kit for the 370Z?


Yes.It will be out next year.We need to gets our hands on a 370Z for prototyping.I might even buy one for myself and sell my 350z.Just got an R32 Skyline,already have a Porsche so I have too many cars

 

Not very popular because of all the stuff you need to make the conversion work which is directly related to an exuberant price tag.LOL.

 

If I get a chance,I will shoot some more video tomorrow of the set-up.It is pretty cool and like I said the throttle response is insane.Another benefit for FI guys is that your stock single TB only open 60-70%(or whatever it is) at WOT.With a twin TB......you get two TB's which open 60-70% which means right there you now have a TB that is more like 80-90mm then 70mm.This is why we did this set-up in the first place.We wanted to get more airflow and still retain the fly-by-wire TB system.


Tim

 

Very, very nice!!!

Why not just eliminate the MAF's? We are using an Option Voltage Output on the F-CON to output a simulation of the MAF signal based on MAP/RPM. Then again, we won't be testing it until Sat., but my understanding is that this works fine. Also, there are other controllers on the market that also can generate such an output voltage, so you aren't just limited to the F-CON.
