i just installed tephra v7,but now the car wont start i have put in the same numbers in the init code and the immobilizer,but still it wont start!

my old rom id was 93660005 and my new tephra v7 rom id is 96530706
thought this would help...

so what do i need to do or what am i doing wrong?

my init code is 0001
immobilizer code is FE03

can anybody chime on this,thanks.

 

I used to have 93660005 and went with 96260709 with only changes to fuel, timing, immobiliser and init, wgdc and load. I'd suggest you go with the same as you will have at least a few CELs. You must pay tephra a donation for it though.

 

it took me 3 days to download the tephra v7 cause to be honest im not good with computers and files and all the .hex and .bin files and i finally downloaded the tephra rom 96530706 and was the happiest guy on earth,then it wouldnt start and i said maybe there are 1 or 2 codes that i dont know off and maybe some will help me..

now your telling me i have downloaded a wrong rom and i'll have problems with and to download some other rom i have to pay for! sigh!

why cant ecu's be simpler,all the rom id's xml files and all the headache!

i just want my car on a tephra v7 can plz someone help me with it?

again my rom id is 93660005, now what rom id should i download that my car starts?

 

no one wants to help?

 

The immobilizer is a hex value. When you put in your immobilizer, did you start with '0x'? In other words, did you enter FE03 or 0xFE03 when you entered in your immobilizer code?

 

i entered FE03 is that wrong?

should i entre 0xFE03?

 

i entered 0xFE03 but still the car wont start, anymore suggestions ?

 

Try disabling the immobilizer in the Periphery bits section (FAA) set it to '0' or if '0' set it to '1', and see if it will start.

 

thanks man it worked! thanks alot buddy!

the car started but now it sound weird almost like running on 3 cylinders and when i let go off the gas it stalls, also the CEL was on and i pulled 4 codes...


P0141 Heated Oxygen Sensor Heater Circuit Fault (Rear)
P0403 Exhaust Gas Recirculation (EGR) Control Solenoid Circuit
P0243 Turbocharger wastegate solenoid 1 circuit
P0090 Fuel Pressure Solenoid Circuit

now what should i do to get rid of these, which settings i nedd to modify in my new tephra v7 rom?

and i havent copied my old fuel and ignition tables from my old rom if i do maybe it will help to ease out these problems?

 

Are you on stock injsctors? what is your AFR reading?, you need to port over your previous tune to the current rom and you more than likely have to adjust your BISS. Search the forums for adjusting the BISS, then go from there. Also You haven't given us enough info about your setup for others to help out.

 

I know that these codes are because you don't actually have either circuit in your car. There are periphery bits that you'll need to disable to clear them. Looks like they're in Periphery0 (FAA) bits.

I'm only trying to help. Also, Tephra put countless hours into making the V7 roms, so don't dismiss the idea of donating anyway

 

no sir, im not on stock injectors, and with the v7 rom the car sounds ugly and the afr reading goes all the way lean above 18 on idle, thats if the car idles, when i let go off throttle it dies.

and im really sorry i should have listed the mods...my mods are:

FIC 1250cc injectors
gt35r turbo
gsc s2 cams
ETS 3.5 inch intercooler
upgraded valve springs and retainers
walboro 255 fuel pump

 

if i disable them the car wont have any problems right?
and i promise if you guys help me to run my v7 rom and fix all the little issues im having, i'll donate 100$ to tephra

 

and i copied my previous ignition map to the new v7 rom, the problem is my previous load scale is 300 this new rom has 350, what should i do now to make up for the added 50 load scale?

and what is the map used for ignition and fuel?

main map
global map
alt map

 

The first thing you need to do is to set your injector size scaling (under 'Main Fuel Setting')and your injector battery voltage latency compensation (under'Global Fuel Settings). Do this and your car should idle somewhat, then go from there.
