Good day I am having some trouble tuning the current tephra Rom on the car, the car is able to start and drive however the map seems pretty stock, see attached.

How ever when I try using a normal stock map the car refuses to start.

 

can you be more specific what you mean by "stock map"? Also you didn't attach anything.

 

This is the map currently on the car which I received when I bought the car, however when compare to a stock evolution jdm rom it seems pretty similar in the tables.


We tried scaling the injectors, checking for boost leaks etc. The car starts and after it warms up the idle drops off and malfunctions.


When we try a stock normal rom the car refuses to start.

 

oh ok you are trying to use the stock rom, I would start by making sure you copied over the Immobilizer code and hex over from the ROM on the car to the Stock rom you are trying to load without any errors.

 

Check the immobilizer as Biggie said. You can either disable it, or you need to copy the value from your stock ROM. Its a Hex entry, so make sure you enter with the "0x" prefix (without the quote marks).
