no ecu build?

[Romdoc1]

You guys aren't getting what I'm saying lol. I want to do as much as I can before I need a new ecu. I'm just wondering what I can do with out a ecu tune

Hi Chez,

Really and truly an ecu tune is really what you will need and here is why.

1. Most breathing mods you will make will in some way require an ecu tune to at least maintain correct volumetric efficiency within the cylinders. For example I have been tuning these cars for 13 years or so and I have found that just adding an exhaust or a filter doesn't really do much until the ecu is re-tuned to account for the changes in how the engine inhales and exhales. An ecu tune will not only smooth things out, it will also maximise the power gained from the additions to the engine (granted the parts added are proven commodities).

2. I know you are avoiding an ecu tune but it will add power to the vehicle.

3. Some level of fuel efficiency can be gained.
