And how would the user know the settings changes accomplish anything?
Leading evidence: 'Replace accomplish anything' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace accomplish anything' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Where are the controls to ensure the settings changes actually produce meaningful gains with acceptable trade off in fuel economy, driveability, emissions.

I can, however, contribute a positive ECU flash experience after of changing intake, headers and exhaust.
Replace parameters in air flow, gas intake, and throttle response

As for allowing the user to change settings on the fly you are asking for a huge amount of computing.

Then there is testing: Proper testing would require huge amounts of time, essentially duplicating what Porsche and Bosch and the uncountable engineering and testing manhours already invested in ensuring the existing engine controller fueling/ignition/valve timing/lift controls/maps work as well as they do.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hey guys. Anyone ever heard of In Motion Tuning heres the website
www.inmotiontuning.com
. Its a ECU upgrade for $300. Thats pretty cheap. I want to chip my car and looking at all alternatives. Thanks guys
I would really really really like to know what exactly (parameters) is changed
in a ECU program. This must be one of the mods that I know least about.
I know they change parameters in air flow, gas intake, and throttle response,...
but what numbers are changed to what new values?
With so much computing, why are we paying so much money, when a proper
software app would help any of us- safely, of course.
I think it is only a matter of time before someone makes a program, that allows us to input
the mods we make (exhaust, headers, etc.), and then we decide how much performance,
or how much economy- again, safely.
acommplish this select one or more the list: engine displacement increased, engine red line raised, forced air induction, intake and exhaust systems enlarged, larger intake and exhaust ports wth larger (or more) valves, more valve lift, earlier valve lift, longer duration, higher compression.
Ecu remap does none of these, except maybe raise red line limit.
There is the potential for an Ecu remap to deliver a bit more HP if remap done on chassis dyno and is closely tailored to the engine's characteristics, this specific engine at this point in time. One would hope the improvement would be present under different weather conditions on subsequent days, through all seasons.
If you want an Ecu remap take car to a shop with a good dyno and a good rep and have car/engine dyno'd before the remap.
Have remap done. Then take car back to previous shop for another dyno session.
Post results. If any measureable difference please supply me with place you bought Ecu remap from cause I want one too.
As for allowing the user to change settings on the fly you are asking for a huge amount of computing.
Allowing the user to change the settings relatively easy. Preventing the user from selecting settings -- in various combinations -- that could potentially harm engine requires a huge amount of work.
Since engine reliabilty at risk and if engine failure occurs at least property damage is at risk.
Then there is a small but not zero risk to the driver and any passengers and even other people on the road should a setup cause engine failure that would result in loss of braking and steering power and loss of control of the car with possibly serious consequences.
The liability risk alone would be too huge to contemplate.
Then there is testing: Proper testing would require huge amounts of time, essentially duplicating what Porsche and Bosch and the uncountable engineering and testing manhours already invested in ensuring the existing engine controller fueling/ignition/valve timing/lift controls/maps work as well as they do.
And how would the user know the settings changes accomplish anything? Just a fill up of good gas can perk up a car. Or a drive on a cool dry day. Where are the controls to ensure the settings changes actually produce meaningful gains with acceptable trade off in fuel economy, driveability, emissions. What effect would having such a system in place have on the car's warranty?
Sincerely,
Macster.
I am not going to pretend that I know everything about ECU flashes simply because I don't do that for a living. I can, however, contribute a positive ECU flash experience after of changing intake, headers and exhaust.
I had a combination of mods which mildly improved performace of my car over the past several years. However, after a custom flash, it completely transformed my car. I have had a few people drive my car so they can compare to their own.
One of the car owner drives a stock 3.6L. Another owner owns a supercharged 3.4L who drove my car before the flash and after the flash. The last driver has the same car as mine moded with similar hardware without the flash. They all noticed the improvement.
They all commented that after driving their car and my car, under the same weather conditions, back to back that there is a significant butt dyno difference. We all know that adding 10 to 15hp on a 300 hp car typically cannot be felt. I feel the change in my car like everyone else who drove my car did.
characteristics and needs enough from the stock engine's that a change to the Ecu fuel/ignition maps (and maybe now intake resonance flap and even intake valve timing and intake valve lift maps) can help obtain maximum benefit from the mods.
This Ecu reflash best done on dyno with proper engine instrumentation unless the combination of mods one the Ecu flash company aware of and has already developed a new remapping for.
Sincerely,
Macster.
