With my mods listed below Im looking to add a greddy 3 row and a intake along with a fuel controller. If the powerhouse racing one a good option and does anyone have any good experiences with it? Im looking for good driveability but trying to but down about 450 on stock twins.

Also will i need injectors and a couple denso fuel pumps?

are you talking about the MAPECU? If not, be more specific. That piece is made by Performance Motor Research in Australia; Powerhouse just sells it.

If you mean the MAPECU, I had it when I had my small single and it's a very good fuel controller which also eliminates the MAF, ie. converts you to MAP based fuel control. Since it piggybacks off the stock ECU (I had a gforce moded stock ecu) the driveability is easy to keep virtually flawless.

As far as 450whp on stock twins, you don't need larger injectors or another pump to do that...as long as your stock fuel system is in good shape. But IMO you'll have to run boost high enough that you'll need racegas to be safe, otherwise the stock ecu will be pulling your timing when it senses knock....just driving and reseting the ecu, driving resetting etc is bad practice imo and will eventually take a toll on your motor.

Thanks alot for the reply. I think we are on the same page as far as the map ECU. I think powerhouse just puts there name on it. Im really looking forward to putting the intercooler and intake on and adding the map ecu.

How much tuning is required on the map ecu? Will it take someone several hours to tune it and will I have the option to run E85 instead of race gas?

Thanks in advance for your reply.

I think the MAPECU can be tuned in a couple hours or less. On the E85 I'm not all that well informed if the MAPECU can or can't...I think it can but look into that further.

The limitation you might run into is that you can't tune timing with just the MAPECU so you have no way to optimize the tune for E85...but I'm not sure what the consequences of just tuning a/f and letting the stock ECU control timing with E85; since E85 likes a lot of timing maybe the stock timing is OK...not sure. Of course you can go with the MAPECU2 which allows some limited timing control but again, not sure how it works with E85.

Now that you mention E85, for that fuel you'll need larger injectors and more pump than the stock 550cc and single denso since E85 needs rule-of-thumb 30% more fuel than gasoline.
