Hello there,
This days I resurected an old project. GSXR 750 '88 EFI turbo. I've made the conversion to EFI before 7 years. In simple words - bike is not fired since then. Somewhere thru years, the ECU was sold (it was Link G4 Atom) and I don't remember why, but probably it should be like this!. So universe flip and previous week I receive unbearable desire to revive the bike. I bought MaxxECU Mini (the cheapest ECU on market...I never liked MegaSquirt), re-pin the new connector, somehow found the old Link file (revive old laptop as far I have stolen the RAM from it) and put the basic data like: trigger angle, type of sensors and injectors.
Yesterday I was able to start the bike (7 years ....not even cranked) and tune some basic thinks. But as far as I remember even whit old ECU , starting from cold was not easy.
If you put to much cranking fuel and warm up..it will flood...if opposite - won't start stable and repeatable.
So basic data of the bike...noting fancy.
GSXR 750 bone stock, but low millage, less 15 000km
GSXR 600 TB with stock inj#
COP aka pencil coils
BOSCH 044 pump
fast idle lever - rise Thothle around 1%
wasted spark
injection is ...all 4 injectors together every 720 deg.
I wonder ...
should I put cam sync sensor and make sequentional inj and spark?
can you share your experiance with cold start of your bikes?
Any tricks from the sleeve ?
Regards
