I recently purchased a 1990 TII with a TO4R single turbo and a wolf ems version 3.1 engine management. My car runs fine with the exception of the excessive gasoline smell in the cockpit. I think my car is running too rich and therefore, I bought and innovative LM-1 wideband. Low and behold, it is running way too rich. The wideband read 9.8 to 10.0 throughout wot running 12 lbs of boost. The a/f fluctuate around 13.0 - 15.0 in 1500 to 3200 rpm when cruising. The a/f also read 17.8 and 19.0 a few times when cruising and not under boost. Anyways, here's where I need your help because I noticed the previous owner did not leave me a wolf manual. He sold me the car because his visa ran out and he had to go back to Korea. I want to know exactly how I can raise the a/f to 11.0 under boost and fix the 17.0 and 19.0 a/f when not in wot. Please give the the exact details as to what menu on the screen I should toggle to. If possible, can someone email me at jprx_7@yahoo and leave a telephone number so we can discuss this. BTW, I do not have data logging. Thanks!!!!!!

 

download the manual for your wolf here: http://www.wolfems.com.au/products/e...ersion3/manual

be very careful playing around with the tune if you are unfamiliar with the basics of tuning a standalone...

 

Thanks for the link. I downloaded the manual and printed it out. The manual says to in order to change a map point..

1) Goto Fuel Map
2) Select option 1 for Map point
3) Hit Set to save

Any, I know to be careful and not mess with anything except of fuel and make small increments on the chages. Anyhow, I selected Fuel Map while driving my car in fourth gear. I hit the option 1 for Map Point and when my a/f read 17.2 and I increase the fuel to that map point. I hit select to save. I kept on driving but the point that I changed still has a problem.

Where am I going wrong?

 

When your AFR's are so lean, it will take a large adjustment to get it richer. Just keep adding fuel until you see a big change.

Also, when tuning fuel, make sure that your ACCELERATION ENRICHMENT and SUSTAIN are turned off....
