Quick question
I need to know if the existing tune is still on the ecu now that I have had to reinstall the program?
I never hooked the pda up to the ecu since owning it. Will the ecu still have the last tune stored in it? And if i hook the pda up with no tune in it, will it erase the existing tune? |
The ECU always stores all it's parameters until you use the PDA to change that by either making changes to one of the maps or configs, or uploading a new map.

but my pda has no maps or configs? so when i hook up my pda that has not tune in it, will it read the tune thats in the ecu already? i just dont wanna hook it up and erase the existing tune?? i hope this isnt too confusing. i just need it to run.... and i dont know what to do.
heres my setup: s4 t2 motor with rotary ressurection streetport s5 bnr turbo stage one walboro 255 with 720/1000cc fmic 3" dp/full exhaust all emissions removed/no ps/no ac (just alt.) tb modded any sugeestions? i know ill have to lean out the 1000cc's but as far as timing goes i clueless |
> will it read the tune thats in the ecu already?
yes. As I said, nothing changes until you manually make a change or load a new map. |
