knock w/utec
When I have it on map 0 (stcok map) it does not knock at all. But when I switch it to map 1 (tbe) and then get on it, at about 4500rpm in 3rd gear it knocks. Why does it do this?

I understand what you guys are saying but yes I have a laptop and a boost guage. I was just trying to find out why it would do this. I do know how to use the utec. But i already found what the problem was. So thankyou for the replys.

btw - this is usually not a boost issue, but a timing issue. Base maps from my experience are conservative on boost, way way way overly conservative on fuel, but tend to be a bit aggressive on timing.

stage 2 base map, 14 degrees in the midrange, 22 on top?
i've got at _least_ 6 degrees on that!
imo, boost is MUCH easier to get wrong because people set their ABC improperly. all it takes is one or two too many turns and you've overshot the target completely.

I experienced the same problems. Here's what to do.
1. Log a couple of runs to determine the boost level when it detinantes. If it's more than 18.2+- it will most likely detonate.
2. Lower your boost. Close the boost controller and give it one turn. Take a couple runs and adjust your boost gradually until you see it at 17.5 - 18.0 pound MAX in fourth gear on your log.
3. Now your boost is set right. If it is still not working 100% then download the new UTEC flash and software.
4. The new UTEC flash and software is 10 times better than the original crap they put out.
5. If this still doesn't work, get it tuned for $500.....it will save your engine and will run perfect.

Out here in not-so-sunny San Francisco we get 91 octane at best and between the way huge over dose of fuel and timing like this, right out of the 4.2b stage4 basemap had a lot of knock up top.Stg4 base timing from 4500-6500
Code:
[-100] [21] [21] [21] [21] [20] [17] [17] [17] [17] [17] [-100] [22] [22] [22] [22] [21] [19] [19] [19] [19] [19] [-100] [23] [23] [23] [23] [22] [22] [21] [21] [20] [20] [-100] [23] [23] [23] [23] [22] [22] [21] [21] [21] [21] [-100] [23] [23] [23] [23] [22] [22] [21] [21] [21] [21] [-100] [23] [23] [23] [23] [22] [22] [21] [21] [21] [21] [-100] [25] [25] [24] [24] [23] [23] [22] [22] [22] [22] [-100] [25] [25] [24] [24] [23] [23] [22] [22] [22] [22] [-100] [25] [25] [24] [24] [23] [23] [22] [22] [22] [22] [-100] [25] [25] [24] [24] [23] [23] [23] [23] [22] [22] [-100] [25] [25] [24] [24] [23] [23] [23] [23] [22] [22]
