The ECU will compensate and correct for modifications.

I was under the impression that you had CharlieX do a tune for you?

 

No, I just got back my car and still have a lot of small thing need to fix (as you know Lotus).

I am waiting for dealer's reply about the S260 upgrade.

 

The computer will automatically adjust for things like atmospheric pressure, fuel octane, air density... but, if you change things beyond the normal parameters you will need a tune (fuel injectors, big pulley changes, etc.)

Small changes, like going to a Stage II exhaust, are handled by the ECU just fine.

 

exhausts are after any sensors, so unless it adjusts the back pressure and even then itd have to do a lot, theres no problem.

people don't seem to understand the difference between the emissions adjustments and the open fixed fuelling modes though, there are no changes done there. but at this stage it'll come down to who you believe


the base idle learn takes 15 minutes,, ie idle it for 15 minutes is the factory recommended procedure, there is no 'learn' after idle, its a complete misnomer the car constantly corrects all the time, when its in closed loop mode.

 

Can the ECU be reset only by the dealer or others that have a tune cable (such as the KoldFire OBII port cable?)

 

Which reset?

 

I am looking for the ECU "learn" reset.

I swear HK everything I search about the ECU and stalling you seem to be within the thread somewhere.

I am going to clean the MAF sensor, but if that does not work I want to try to reset the "learn" as the vehicle is a new car learning trim codes.

 

Hello!

Normally only the Lotus Scan 3 or TechCentre OEM diag systems are able to make an ECU reset.
However we have included the function in our reflash cable, that will be updated with some diag functionality soon.

Cheers!

My cable has been used for many reflashes while Phil @ BOE was getting it all just right, that functionality has worked great. I am very much looking forward to more diagnostics and hopefully logging functions. What is the plan for the software in the future? When will we see the diag functions released?

 

I think I am going to buy the cable and be done with this. Then if I need a tune do be it.

 

^^^^ Why do you keep reflashing? What type of car do you have?

 

I'm thinking he has an Elise or an Exige w/ a REV 400 TVS supercharger. I bet it is quick like a bunny. I'm also thinking that there may be different states of tune, for different power levels, that you load from your laptop w/ the Koldfire software and OBD/USB interface cable that is included with all BOE blowers. Each with it's own flash load. But I'm just guessing.

 

HK, Did you get the dealer to do a 260 flash for you?

 

Yes.

If you have S240, then you will be fine for fuel pump + injector.

If you have S220, then you need to upgrade the pump + injector.

 

HK, Thanks.
The local dealer says it's easy, BUT they won't do it.:sad:

 

Unless I'm mistaken ( happens more often than I would like to admit) you can get someone else to do that 260 reflash for you. Unless it's a warranty concern.

 

It is a warranty issue (2010). That's why I wanted the dealer to do it.
I guess I'll wait for warranty to end and then ......

 

I just bought the Kold-Fire cable for this feature and the additional ones expected per BOEs website.
