The previous owner of my 240sx disconneted the speed signal wire to the ecu. Will this cause problems with my tuning. Does this effect closed loop operation??

My vehicle has the s13 sr20det red top. I ended up having to install NIStune Version 0.9.3.6.1 (which everytime I load tells me it will expire in x number of days) . I used a saved copy of my tune to get the car running again. I'm glad I was at home when this happened or I would have been stranded. ...

I downloaded the new fixes that were posted on 9.8 b. It came up with some new window about merging images and I selected yes and then my car shuts off and won't start. I have no car now what the hell is going on?

What is this tab under the knock copy in the fuel map for? Am I missing gear tables for my s13 sr20det 50F00?

Ok awesome, this seems to add quite a few tables to the mix including,
Decel loss ratio
Decel loss RRM
Decel loss temp
Closed loop Cut
Injection response
Low AFM volt enrich

If anyone has experience adjusting some of these and cares to share their findings please let me know.

So how can we get those added?

I want to take it off so I can better tune my maf translation when reading logs. I want to modify my maf translation that way when I command an afr number I get that number or close to that when I'm driving. Otherwise its just an arbitrary number in the map to get a desired afr. Most professional tu...

I just looked at TP load limit and I'm not sure how that would turn off my deceleration fuel cut. I want a table that allows the engine to maintain set primary fuel mixtures when I let off the accelerator to decelerate.

I have a Red Top Sr20det that is installed in my s13 240sx. I'm using the real time type 3 board for it.

Thankyou for responding Matt,
Where exactly is this "Fuel Cut" table located, I see no table in the lists to the right on Nistune by this name. I see "TP load limit", "Increase fuel","ttp max/min" But no "Fuel cut".

I'm going to calibrate my Z32 maf translation and I wanted to know what table and what inputs I would have to make to turn off the (DFCO).
