Precautions when removing the s300 board off the ECU.

[fabioborges87]

Hi.

I need to remove the s300 v2 board from the ecu and store it for a couple of months.
Is there anything i should do to prevent problems later when i re install the s300 board into the ecu?

I'm asking this because i heard some people saying that after they leave the car in the garage for a couple months with the battery plug off, and when they try to start the car, the car doesn't start and the board shows the red light. They say the problem is the small battery in the s300 board itself that runs out.

Is this true? Can i carefully remove the board from the ecu and store it on the original package inside the anti static bag with no other precautions?

Thanks

Why do you need to remove just the s300 and store it for several months?

The battery powers the keep alive memory on that version s300. It uses the same power in the ECU or out of the ECU, so removing the s300 from the ECU will not prolong the battery life.

Because i currently run an b18c, but im going to swap it for a b16 to do some work on the engine. i have a map for the b16 but its not made for hondata and i only have 1 ecu.

The s300 is a fully tunable system and you can easily upload a different calibration to it to run the other engine you are putting in.

So, i upload the map which was made and save it in .bin format and load that map on the smanager right?
And then on the Parameters tab, respectively on the Fuel compensation, Fuel Trim (this motor have b18C6 stock injectors), Gear comp., Idle and Ignition Compensation i need to change something aside from the rev limiter and vtec engagement?

No, you cannot load a calibration made using other software. But you can just go to the new calibration tab and start with a stock B16A calibration and modify it as needed.

But i do not know how to make these modifications and that's something i don't want to mess and blow the engine.
The tuner charges about 250€ and i don't want to spend that money on a engine that's only going to run until the summer.
For now i already made a socket that plugs in the same socket that the s300 does and i'm running the old map, 190hp on the dyno and its all ok.
Now i'm going to start rebuild a b18 and when its finished i will put the s300 back on the ecu and take the car to the tuner...

if you have the stock o2 sensor in place I'm sure you could just load the stock b16a tune from within the software(new calibration) and set the closed loop parameters to (stock Narrowband) to run under all MAP pressures(by default it's adjusted so it doesn't flip to your wideband, and the car will run like a stock b16a, correct me if i'm wrong anyone.

for example, set your conditions to Max MAP for closed loop = 1 (psi) (because you'll never go above 0.4 inches/psi and
max engine speed 9000 RPM

and on the options select closed loop - stock sensor narrowband
narrowband target voltage is 0.51 verify with the internet what your stock sensor voltage is for 14.7 AirFuelRatio
