the table is low pulsewidth injector offset adder v.s bpw , don't know what this table is for? and do I need to adj it for my svo 24# inj ? it is at the stock setting now

 

I don't really know. Never messed with that table. I'll take a guess though. The BWP is the injector base pulse width in micro secs. Why micro seconds? I don't know. I have only seen people talk milliseconds. The "adder" is the amount of time to add to that perticular base time when doing a correction for the next go around. The bases are 10ths of a millisec and we all know that the total pulse witdh is around 2 or 18 millisecs depending on load. Most of the "adders" are above 1 millisecond though so this table must be very important. How this ties would be nice to know.

someone has to know what this table is for !

 

The table is for you to leave alone.


Seriously, if you don't know, don't mess with it. Never heard of anyone doing so. If you injectors need to be adjusted, they are to be adjusted in the Constants.

Not to hijack a thread, but I was curious about a constant...Its SPARK REFERENCE ANGLE. I haven't found any info about it, but was curious. Could this be a compensator for installing a cam advanced or retarded? Its been 0 in every map I've looked at, so I'm not too sure. I know the Speedpro has a crank reference angle, which if I remember right is 6 in an LT1, and we had it at 50 on a mustang my friend has. Anyone???

 

never seen that table in tuner cat?

 

Its not a table, its under the constants table. Its almost at the very end. Not sure what it does, but I may play with it sometime soon.

 

Fbody1..I pm'ed you a question about another post. Anyway, I went on a mission and this is all I found anyone had said about it. I do not know how true/false this is either.

"This table adds a bit of injector opening time to correct for the time it takes to fully open the injector. You only need to adjust this if you change injectors (for example, the SVO injectors take longer to open, so you'd increase the values slightly to compensate for this)."

I don't see that table in Tunercat my ecm is 1227165 and my bin is ARAP $6e (may not be used for MAF.)

The time it takes from receiving the pulse and the injector opening is called, "Injector dead time," which varies with injector type. This is highly dependent on battery voltage. The injector Pulse Width correction vs battery voltage is in micro-seconds and is as high as 5.7milli-sec at 6 volts, but I don't think that includes the dead time offset. Haven't found the dead time for the Accel 30# injectors I have. I'll call tech support on Monday and edit this reply.
