Sounds like the Camry needs more time to be tuned well.

Here's my question regarding SGI kits...
For example on my Mazda 3 it has a O2 sensor. Does the A/F mixture "Adapt" / Change in real time based on how my engine is doing?
Does the ECU do this thing?
I'm thinking sana my Mazda 3 conversion has less problems kasi its a newer model that's more compatible with the SGI kit.
Well, the factory ECU is still doing it's "thing". The SGI kit reads the signals and adjusts the lpg flow based on the factory ECU signals. The LPG ECU simply corrects the amount of fuel flow per cycle.

As for the Mazda3... the M3's ECU is uber sensitive. Even our Mazda3 1.6L still experiences occasional CEL (check engine light) at around once every month to once every two months. Other than that, the car runs pretty well although it experience initial problems like power loss and stalling until the LPG kit was tuned by SPEEDLAB.


In the case of my dad's camry the A/F mixture is like Pre Defined so it doesn't know to change the A/F mixture when needed?
Does it act like a SGI kit? or like a Open Loop lang? (na Fuel Injected)
I am assuming it's using the SGI kit so the LPG system is simply following the stock ECU's signals (which is what it is supposed to do). Just bring it back to the LPG installer for another round of tuning or bring it to SPEEDLAB if they have the software tuning kit for your SGI system.
