Hi,
My car FJ80 cruiser fitted with LS430 V8,
Now the guy how tuned it for me recommended the elite 550 ecu to me that time i know 0% about AFR but now i see he picked bad ecu for my car.
I wonder how he did the firing order here?
And the ecu has no lambda sensor !!
Can you explain what the tuner did while tuning my car
Also plz recommend an Air fuel ration sensor that can be used for dyno if the car are not fitted with one or the ecu dosnt support it?
Thanks
Hi Ali, you may want to purchase a AEM o2 sensor and monitor, they are very common, and you can see the state of tunning and monitor while driving.
Wideband sensor kits are often sold separately from standalone ECUs, so that is not uncommon.
