However, I have been after Sniper for the datalogging updates and when I get their software sorted out, I'll pick up either a LM-1 or Sniper's Wide band kit.

 

I've got another question, will the sniper software allow you to tune the FICM? The guy that I have been talking about just was able to do his own software that allowed him to tune that as well as his normal custom tuning. We spent about an 1 hr and a half testing and tuning after I got the new turbo on.

 

I don't know what your/he's working with in the fuel injection control module. I have the gas program only, but I can adjust for return or returnless fuel pressure, injector size, MAF calibration and location, low/mid/high fuel mod, low/high/rpm spark mod, and global spark and fuel modifiers, along with other features.

 

Pulse width with the FICM tuning; what other stuff you mentioned he does as well(those that would apply to diesels mind you) and I'm sure more, my eyes just kinda glaze over when he gets too technical.

 

Reax,

I suggest you make no tweaks to the air/fuel ratio, other than enriching, until you O2 datalog. You can safely enrich it, but you cannot safely lean it without knowing what lambda the engine is running.

 

The files are done and I have been pretty happy with them for a while now. Thanks for the suggestion.

 

I have the sniper as well. Started with the special forces and upgraded to the Delta force. I have way more control of things than anyone ever needs. lol One nicety for the 98 was to control up AND downshifts along with torque convertor lockup & unlock. Changing from 3.55 to 4.56s threw that all out. Had to do manually sonce onl 99 and newer can adjust electronically. The best change was to remove the torque control feature. Watching the timing pull back to 0 to -5 (yes ATDC) during shifts made much sense to the trans behaviour.

But there datalogger need a lot of work...

 

The reason I mentioned it is because with a too lean tune you may think it drives just fine, all the while a valve is slowly being burned, or you hole a piston on a hot day when the engine momentarily spikes lean (which happens all the time since the stock O2 sensors aren't terribly accurate).

 

I have an Xcal II and Troyer custom tunes and have never regretted the decision. Give the folks down there a call if you haven't already, they are great and will spend as much time necessary talking to you and answering all of your questions.
