Understood.
could it be a possible hard coded fuel cut /recovery as seen in Hondatas?

I am still unable to get the AFR to communicate with the laptop at the moment due to windows 10.

Hi Matt, I got the timing values solved and understood what you meant. But as for the fuel cut/recovery, it does not seem to change anything significantly. let's say fuel cut 3500rpm and fuel recovery 3200rpm, I am off the gas at 3500rpm, afr goes to 22.0 but doesn't recover to 14.7 at 3200rpm until...

Hi Matt,thanks for looking thru it. I am trying to raise the fuel recovery and fuel cut to compensate for the light weight spec flywheel. Car tends to stalls out when clutching in and off the gas. Raising the fuel cut to insane rpm range and fuel recovery did not have any reaction. Hence I am puzzle...

Hi Matt,
I have sent the file last Friday. Do let me know if you find any thing in it.

Hi Matt I am unable to PM u the map in the forum.
Is there another way ?

Hi Matt, need your help on this. I have been playing around with the Fuel Cut and Recovery function in the JDM S13 CA18det map. I have set both to 6000rpm. The car does not seem to react to this after uploading and burning the map in. 1st gear moving up to 3500rpm and letting off the gas would have ...

Fuel cut table values are higher than recovery values (the table names were wrong way around) When the RPMs drop the fuel is cut for a short period of time, and then it resumes injection at the recovery point. Thanks Matt. Perhaps I can try readjusting again to see if I can smooth out the decelerat...

Don't confuse TP (load cut) aka boost cut (which cuts fuel on acceleration) with Fuel cut/recovery Fuel cut/recovery do a small amount of fuel cut on deceleration (when TPS idle) to avoid injecting when throttle released. For example @ 80degC Ctemp: 1200rpm cut to 1100rpm recovery Just noticed tabl...

only swap the table names in next update Timing ascending values are nissan defaults in that table. Right click and 'filter' the values to see BDTC Hi Matt, has the table name swap been implemented? Just to clarify, the 2 tables you mentioned are the Fuel Recovery and Fuel Cut tables? Meaning their...

Thanks Matt, will run the next update when I get the laptop into the car again. Will try to adjust the fuel recovery again. Raddy, I have advanced the timing for the deceleration vs rpm map. Seems to have improvements over previous setup but not 100% on the issue. Any idea how far advanced can I go ...

Thanks Matt. Seems abit clearer now. I tried to adjust fuel recovery to a higher RPM so as to get it to catch the engine from choking down to 600 rpm before it slowly bounces back up due to that light weighted flywheel in the car. As for fuel cut, I left it much alone for the moment as I have yet to...

Hi Matt, quick question on Fuel Cut and Fuel Recover. For the Fuel Cut, setting the value (RPM) at which fuel is cut when it reaches that RPM value ? Fuel Recover, as I read in the manual, points at the rpm which the fuel injection resumes. Would raising the Fuel recovery rpm mess up if the Fuel Cut...

Right, so there is the values for Idle/Decceleration when TPS is on. Moved the timing up for rpm range 600-1200. Question: Won't I have to try increase it up the range as the car is decelerating? An observation: When my car is started up, she revs fine, doesn't dip when the temps are cold, but once ...

Hi Raddy,
I'll check it again.

Kinda messed up abit of the tables which led to not so ideal AFR of 14.
Thanks for the tip.

Has anyone else tried to compensate for a lightwheel flywheel?

Hi Matt and Randy, Tried to raise the ignition vs rpm. Seems to help better. I also tweaked the fuel recovery higher at 1500 rpm. I am uncertain about the Fuel cut which is set at 1400rpm. Does this affect as the drop still is harsh. Lastly, ignition vs rpm has 2 set of value row. Not sure if I am d...
