Injector settings
So i have been tuning in some new injectors. Im using these 650cc denso injectors from KSM motorsports which are plug and play for the stock Airtrek. Pretty cheap too at $200 AUD
The seller provided latency data but i found that needed some fine tuning (wasnt too far off). Im using Merlin's tuning guide as per the start of this thread for the tuning method.
Here are the settings im currently using.
609cc scaling (Ecuflash)
Injector latency vs voltage
Im getting pretty accurate fuel trims with these settings. Closed loop at idle and cruise is almost spot on. Open loop is running pretty close - around .5 to .75 of an AFR point leaner compared to the ECU fuel map.
The other tables to change all affect your cold and hot start. So far cold start and hot start are fine but...half warm seems to rich so still playing with that.
I wouldnt instal these without being able to confirm the AFR with a wideband but they are working well for my setup.
Hope this is useful! If anyone has any advice for other tables keen to hear it

Yes i just did that but the cel and p0403 code kept popping up when start the engine. Tried clearing it several times but it came back as soom as is start the engine.

Do you have the EGR enabled or disabled? With those roms the EGR bit should be enabled BUT all the tables are zeroed out. To my knowledge if the EGR bit is disabled it will throw a code that can't be permanently turned off.

tried it both ways (0 and 1) and cleared the code but when i started the engine the cel turns back on and when i scan it shows the same p0403 code. did you guys remove all the egr solenoids in your car? and do i still need to buy and install them since mine are dead when i got the car because that cel is really starting to get on my nerve.
