IP Full Load Adjustment Procedure for the MW and M pumps
I have a two of the same and I was able to tune them to be quite pleasure to drive. I had a one at first and it was very docile. I accepted that how it is. Then I got a second one with seized engine.
At first I thought that engine is toast and I need to replace it. After I opened up engine I found that timing chain do to wear on camshaft sprocket jumped and consequently broke the chain. To make story short I was able to resurrect that engine. Once I got it running I decided to give some more fuel so I adjusted fuel screw 2.5 turns. Well, results where just outstanding. Difference in between my dd and new acquisition was like day and night. So obviously I wanted to know what made such a difference. I adjusted fuel up on my dd and it was some improvement but not close. So I checked engine timing. I have those clamp on piezo sensor and I was surprised that my great performer timing was 23 deg. BTDC at idle! Then I check static advance and it was 6 deg. ATDC. I went and advance timing on my dd but couldn't get close so I ended up with 19 deg. BTDC. I went for test drive. Difference was remarkable. Boost comes very early and car just goes. My fuel milage dropped by whole 1 liter to 8 l/100 km in town! I still drive with this tune and after adding CeraTec fuel consumption dropped additional 0.2 l/ 100km. This is was first time ever tuneup in the can delivered any results. Engine runs quitter and smoother as well.
I know this is way out of what factory settings are and anybody would recommend. Just saying this what I have done to my cars and it works for over two years.
