Which Perfomance Ecu To Go With?

[Astroc2002]

Been wondering which company I should go with as far as a Performance ECU Upgrade, I was told that some of Jim Wolf Technology's ECU Upgrade may not state it's smog legal in California, but no one has ever complained about their ECU's not passing smog in California. Now Jet Performance does have both an ECU Upgrade (C.A.R.B. Legal) and a Module called the V-Force Plus (Legality Unknown at the moment, sent message inquiring legality and if device will work with there ECU Upgrades).

 

Now I read an article in Nissan Performance Mag. that some guy in southern California with an older Pathfinder than mine with almost the same performance upgrades such as: 264" Nismo Cams / Doug Thorley Ceramic Coated Headers / Nismo Cat-Back Exhaust / Jim Wolf Tech. ECU and saw MPG's in the high teens to low twenties in city and low to mid twenties on highway.

 

Now I'm not running performance cams in my 94 Pathfinder LE 4x4 V6 Auto., but I am running Nology Hotwires Spark Plug Wires / Doug Thorley Ceramic Coated Headers / Flowmaster Two-Chamber (40 Series) Cat-Back Exhaust and a Jim Wolf Technology Pop-Charger Cold Air Intake. So if anyone in California with a Jim Wolf Technology ECU Upgrade or a Jet Chip in a Pathfinder or Pick-Up powered by a VG30E and Automatic Transmission, please help out by giving me some advice or pointers on which company to go with.

 

P.S. Yes, I am currently smogging my Pathfinder in California under C.A.R.B. Regulations even though it states that it meets U.S. Emissions and not California. I traced the vehicle being first sold in Texas.

Honestly, without a cam I think your stock ECU should be able to adapt to your existing changes just fine. Make sure your MAF is clean and your o2 sensor is new and then re-set your ecu by leaving the battery unpluged for about 4 hours. Before plugging it back in turn the key and hit the bakes a few times as this ensures the drain/ reset process is complete.

once re-connected you ecu will re-learn how to manage you engine based on the readings your existing mods are giving the sensors.

 

If you are have a "cali model" rig I have heard you can try running a federal ecu for a little more kick and just go back to the cali ecu if it fails emissions. Just be sure you let the ecu have a several driving hours to get itself fully efficent before you smog test.

Well the O2 Sensor was replaced with a new one when I got the headers, but I'll definitely check MAF to see if it's been damaged or if there's any grime deposits on it while in the process I'll check the Throttle Body Flap. Now my question is what to clean the MAF with if there is deposits on it, I already know how to clean the Throttle Body. My friend told my to use brake cleaner on the butterfly flap of the Throttle Body to clear out the grime. However I don't know what to use to clean the Mass Airflow Sensor. But thanx for the tip on how to reset the ECU and resetting the brakes. I'll give it try today to see if it will solve some of the problems its experiencing.

Use alcohol on a Q tip to clean the MAF fillament, just be very gentle!! I just cleaned the MAF on an R50 yesterday...

Both of my pathys were from out of state and seem to pass Cali smog without trouble.

 

We will see how it goes with the Thorley headers, high flow cat, flowmaster, etc...

if / when you get a different ECU,

 

Go jim Wolf.
