It is a premium, I saw no need to buy a car with options I would just replace ;)

subscribed. this thread is going to produce an amazing monster i am a huge fan of the genesis.. are you going to be lightening it up or leaving it a street car or what?

Looks good Sean. We have a Genesis 3.8 at my work right now for a test vehicle, and it's a pretty sharp car. I'm looking forward to seeing what you can do with it.

i drove by your shop last week in my fc. I think you were getting into your genesis and i think you driving behind me until i pulled into my friends shop's lot.

cool
 
looks very nice. As always you guys do great work. Curious, once you get a full standalone, have any plans to make an intake plenum? Also, why not try a EMS like a Haltech or something similar, until a PnP unit is made?

I was wondering how the throttle by wire was going to feel about massive amounts of air pumped into it on stock ECU... Also is the ECU run solely on MAP? I don't see a MAF on it?

Unfortunately there are many reasons why a typical standalone will not work with this vehicle. One of the reasons being drive-by-wire. Although there are units out there that will work with DBW, they are not compatible in other directions.

Yes, the ECU runs off of two MAP sensors. Right now our biggest problem is the factory ECU wants to step in and take control, which makes tuning the FIC very difficult. If the ECU sees something it doesn't like, it has the ability to close the throttle regardless of where the gas peddle is.

Would an AIC work for you, that way you're not altering any of the MAP signals, just supplementing fuel independently of the ECU?

Or even better, a meth injection system, that way it helps with some of the concerns about timing and higher boost on stock ECU.

Rx-8's are drive by wire and have a million things running off the stock ECU like intake valves etc and we get them to work. I have the OEM ECU controlling the throttle body, tcs/dsc, power steering, APV, etc...and I have a microtech controlling the engine functions. I keep the Stock ECU getting signals from the sensors but the signals it sends out to injectors and ignition etc go to cut wires. Its worked great for the past 3 years and I put down over 500whp on E85.

The CEL is on but only because the OEM MAF is still connected to keep the OEM ECU happy and it reads gobs of air going through so ti throws a CEL here and there.

thats the only Hyundai i would ever buy other than the 4 door sedan

Brody8877 09-12-09 01:19 AM

I was on the genesis forum, alot of people saying that the internal will not support more than 350rwhp safely. What is the motor setup?

Sean built a manifold for me a while back and its still kicking, Excellent work guys
