Performance chips for volvo Penta?

[Dmax27]

I have a new boat on order. Its a 22' Fourwinns Horizon with a 280 HP Volvo Penta. Does anyone make a performance chip for boat motors? I have a chip in my truck that boosts the horse power and torque. The 280 HP is a 5.7 <br />liter so is the 320 HP. What is the difference in the motor besides the HP? Thanks for any help in advance.<br /><br />Dmax27

Im not sure about the chip.<br /><br />The 320hp engine is MPI (multiport fuel injected). Your 280hp is TBI (throttlebody injected). The difference is in air flow and six additional injectors.

The Motor I ordered is the 5.7 GI 280hp with fuel injesction. I found an article on line that compared the 280, 320, and 375 Volvo Penta. I think the article was in Boating Magazine. The article said they changed the camshaft and exhaust manifolds to get the extra 40 hp.<br /> I see a lot of chips for cars that boost the power. The chips make changes to the ECM to get the hp boost. <br />Dmax27

Re: Performance chips for volvo Penta?

There are no "chips" available for any marine application. The ECM has to be reprogrammed by "reflashing" the EEPROM. There only a few places than can do it, and there is little or nothing to be gained by reflashing the ECM without other mods.<br /><br />Dave

They are both MPI engines, no TBI's since 2001 (I think was the year) The cam, pushrods, valves, fuel injectors, etc are all the same for the 280 and the 320. The only thing changing is the ECU and the max WOT rpm. The Gi only goes to 5000, the Gxi goes to 5200.<br />Here is a link to the Volvo site. Look at the product bulletin for the rpm's. The parts information I got from the Volvo parts catalog.<br />Your best bet would be to order the boat with the bigger engine in it to start with. If you go messing with the ECU, you void any warranty right from the get-go.<br /><br /><br />Volvo Penta 5.7DP

Re: Performance chips for volvo Penta?

I won't do any changes until the boat is off warranty. The up front cost for the 320hp is about $2500.00 more. I'm sure I could have it reflashed to change the max rpm's for a lot less. If I have to have it serviced I'll have it flashed back to stock. <br /> I only ask about the chips because there is a large market out there for them in cars and trucks. Think about it, if you could put a chip in your boat or reflash the ECU and get a 40 hp gain for $400.00 or less. Thats about what you would pay for a stainless steel prop.<br /><br />Dmax27

just because there's a large market doesn't mean it works. do you know what the chips do (if anything at all) to gain the extra power?

Re: Performance chips for volvo Penta?

cars have emission controls and marine engines dont yet, thats why most marine ECU´s dont have a chip they are already desined to run at WOT. double check all the part numbers before just reflashing and ECU. some engines had a cam position sensor and some did not and sometimes you will find throttle body and injector flow rate differences to boost HP that just an ECU map change will create a failure Muy pronto.but its your motor. but best I remember when an ECU is flashed it also eliminates any stored codes as well as engine run time, bring me a motor with no codes a blown piston or a burned valve and zero hours and my first call is to volvo penta for further instructions and ask if they wish to inspect anything before I proceed.<br /> same as I do for all the rest.

Interesting comment above from Don re the difference between the 2 engines, if he’s right (I sure aint gunna argue with ‘him’) You may be able to fit the ECU from the 320 to your 280 providing the loom is the same............

There's got to be more than the programing in the chip to sell for $2500.00 more.<br /><br />

If I have to have it serviced I'll have it flashed back to stock.

If it's still in one piece! <br /><br />

Yes, but do they really work? How would you know without sophisticated test equipment?<br /><br />

Think about it, if you could put a chip in your boat or reflash the ECU and get a 40 hp gain for $400.00 or less. Thats about what you would pay for a stainless steel prop.

So why doesn't the manufacturer do this in the first place and either increase his profit or cut the price to be more competetive?

The GXi has longer rockers to get a bit more lift out of the cam. I think the Gi has 1.5:1 rockers and the GXi has 1.6:1 If true, the different rockers will open the valves 6-7% more at the same duration. The difference will only be revealed at the top of the rev range, hence the need to rev the GXi to 5200 RPM to get the extra power. <br /><br />There is no linear correlation between cost and HP when it comes to I/O applications like there is in OB applications. Look at the price jump from a small block to a big block. Ouch.

Changing of the mapping works on cars, when you drive a 135hp 2 ton Landrover and chip it and get 200hp you can tell the difference its amazing. The extra Bhp comes at the cost of economy,

Why is someone... always trying to get something for nothing?<br />(not directed at Dmax... just an observation)<br /><br />Does that boat cruise at a different speed/fuel economy with 40 more hp? Or... do you intend for it to ever see less than 100%TPS?

Lots of manufacturers sell you things at different prices that are the same but with different software. If you change the software you get avoid paying a huge margin to the manufacturer. <br /><br />Regards chipping of cars, the mapping is designed to be jack of all trades you may want your car / boat to be master in one area. i.e you want power but are not worried about fuel economy.
