360 High Performance Factory Upgrade ECU's

no way a chip can add 48hp on a modern naturally aspirated car.

 

Did you have any noticable performance gains, problems, bad experiences, Why wasn't it a smart buy?

 

48hp is within reason, especially on higher horsepower cars. Horsepower on the ground, you could see a 39whp gain. However, Factories are known to inflate horsepower ratings. By altering the A/F ratios and ignition timing, that gain is possible, with better over response from the engine as well. But I would like to see a dyno sheet of before and after with the stock Air/Fuel ratios, as that does seem a bit high.

I am not sure of the Italian deisgners and their fuel system setup with concern to consumption, but if you think that most cars get at least 5-6mpg more than that, like the Corvette or Viper. Given, they are not the best examples, but there are really no other 400hp factory cars.

The 2004 Vette has a 5.7L engine, makes 400hp, and is rated for at 19mpg/28mpg for fuel consumption. The 2004 Viper has an 8.3L motor and makes 500hp while rated at 12/20. So the Viper is over twice the engine and has better mpg. It would seem that based against these cars that the Modena's exhaust is very rich. And by leaning that out to a safe level, it would both increase mileage and performance.

I do know that the Evolution gained 50awhp on the dyno with a A/F tune alone, but that is a boosted car. For the Ferrari's, Hamann offers ECU chips for the F355 (25hp) F456 (30hp), and 512M (35hp). But I have no performance specs for those regarding horsepower and fuel consumption.

 

at the most, .2 seconds.

 

i can't find it?

 

thanks. so the "up to" 48 hp increase requires cat and exhaust replacement. as well, this is probably not CA smogable. a lot of 360s fail CA smog testing already. this would probably make it a certain fail.

 

The failure of CA emissions is due to the test pipes and aftermarket exhaust. That alone would give ~25-30hp. And tuning the A/F ratios (which is what the ECU does differently) gains more power because of that.

 

increasing the red line to 9200 would only decrease engine life...its called common sense...and changing a 360 exhaust doesnt increase hp....i doubt you really get 48 hp changing the ecu!!! then why didnt ferrari do this in the first place? and a lot of these aftermarket tuner companies stats and dynos are bogus...andything to make a buck..there are ways to increase hp andtorque, but they are not cheap and they do decrease car and engine longivity, not to mention.decrease resale value.....

 

most 360s are never driven enough miles for reduced engine life to be an issue anyway.

as far as the 48 hp for ECU only, doesn't the ad say 35 for ECU alone?

ferrari may not do this from the factory to comply with emmissions.

all that said, i don't disagree with tuners propensity to be liberal with the truth with respect to performance claims.

 

There's a whole lot of 'smoke' surrounding reported gains in HP from chips.

First, what's important -- from the perspective of increased acceleration and kick -- is NOT HP but changes in ft/lbs of Torque, and where that is located on the rpm band. W/o a dyno chart showing before and after 'rear wheel HP and Torque' you can't discern where the purported gains are. A 40 HP gain way up at the top of the rpm band alone won't necessarily translate into increased acceleration.

Second, tuners use a 'formula' to translate rear wheel HP and Torque gains into gains at flywheel. Flywheel HP and TQ are what manufacturers report. Question is, what forumla did they use. Often the gains at flywheel are overstated. A standard conversion rate is 15% loss in the drivetrain, meaning 100 rwhp on the dyno would be translated into 115 HP at flywheel.

W/o before and after dyno results, and w/o seeing the HP and TQ curve from those dynos, don't touch the product. It's probably a scam.
