about injectors - i believe that my is not 480 cc, when i put your KCONST and latency, engine starteb but after warming up mixture became too lean ang engine is stalled, but on stock KCONST and latency engine works pretty nice, and one more thing - when i resized maf, scales changed themselves and there was very nice dynamic, when i put scales from your file dynamic decreased much

theres a tickbox for the MAF rescalning. You can disable that. I'm thinking of disabling tickbox by default. Seems to cause more problems than help

Interesting with the injectors also. See if your injectors are the same in the PDF in this thread which are the ones I have

Purple R34 RB20DE/T NEO 16600-RR710 with picture. Should be the same. Not sure whats going on then?

yes, i also think, but now thire is pure understandig in rescaling and there is no problems there

soon, when they will repair supports, i will ask to remive one injector and will compare with picture in pdf (now i didnt remember what they looks like)

thank a lot again for helping me ))))

hi, today a have done some road tests to rescale TP properly, ang get log of the last one, there TP is always 136 - straight line, because of what it can be ? log is attached

Firmware problem in the board when using Stream Mode. You will need to use 'tuner mode' in the meantime when logging (yes I need to fix this I've noticed on my car too)

ok, calmed me )

hi )) couple questions again 1) about VE Map - should i "reset" it, make all values at all map - 100 % ? 2) what o2 feedback means in timing map and why (when we turn on FLAGS) marked area is not the same as fuel map; in fuel map, as i understood, o2 feedback means that mixture seeks to 14.7 and these values ara in the map in marked area (when FLAGS turned on), but i just cant understand what is going on in timing map

thanks for answers in advance )))

ps i am almost tune my fuel map, tomorrow going to tune timing, i will put results here when we done

Have you read the manuals (mapping guide and software manual?)

O2 flag not used for R34 at all
Knock flag is a flag where the ECU looks for knock in the timing maps

VE map should leave 'as is' when adjusting just the fuel map. Its used to trim the main fuel table

yes i have read all manuals for several times but because english (especially australian english) is not my native i could not understand some phrases and expressions even with translator, sorry )))

now clear about flags and ve map, thanks a lot

hi again, yesterday i did some road tests (we dont have dyno, nearest is over 250 km and costs 200 eur per 8 hours) and got some questions 1) why mixture richs before shifting (see attached image) ? it makes trouble - eg temp increases higly up to 950 celsium degrees



2) on boost ignition timing does not match to timing map (see attached image)



3) matt, can you check out my tune, if its ok there or not

logs and image file attached

check that the ecu isnt going into knock maps.
check your timing on your knock maps to see if it matches, also check the ecu fault codes

knock maps are the same as regular (copied) how to check ecu fault codes ? if there is some software ?

Fault codes in the Display - Consult vehicle display

Those spikes are your MAF reading reverse airflow (reversion)

This is a common issue and it means that you need to point your BOV vent back away from the AFM and towards the turbo (at an angle)
