SLP PCV maps

[pura vida]

running the slp single with the 0-3000 foot map in my pro. thing seems pig rich. belches black smoke and spits five after i shut it down following a hard run. anyone else notice this with their maps? i have the utmost respect for slp and know the do almost more testing than anyone else out there but they also must produce for the masses so i would think there could be some room for improvement. also when i looked at the maps themselves they seemed pretty complicated. pretty large fuel change jumps over small rpm changes and throttle positions.

i have a head i'm planning on adding and was looking at the 5000+ foot map for the pipe and head and was surprised to see that it was significantly richer than the 0-3000 foot map with just the pipe. i was under the impression when a head was added the mapping actually need to be leaned down b/c of improved efficiency. (assuming of course they are both pump gas heads for your elevation/similar compression) plus i know it needs to be leaned down when you go up in elevation. just seemed strange to me, am i missing something? thinking about picking up an autotune and see what that does. (see other thread). thanks

I have had the slp stage 2,3,and 4 kits on my sled every map I have gotten has been spot on. I did have a problem with my sled after I installed the ported cylinder and sled just seemed pig rich as you stated. I had no engine codes so I checked out the whole sled ohm'd out every electrical part on sled and all were within specs except for the pipe temp sensor it would read ohms but the reading would fluctuate when I had a constant temp on the probe such as sitting on a rag on my workbench and had not been ran. This sled ran perfect last year when I put it away. When installing the kit I did not remove the pipe sensor from the pipe so who knows how or why. I got a new pipe temp probe and checked ohms and they stabilized on the new probe just sitting on the bench, where as the old probe they just bounced around continuosly.

I would say pipe sensor or TPS needs to be recalibrated. Not sure why there would be maps for different elevations unless you mean a different elevation head. The atac thing i think its called on the airbox should compensate for elevation and air temp changes. I second that the slp maps are spot on from what I've seen. Hit up Justin I think he's code red performance and has good info on slp polaris stuff.

hmmm, thanks. i just went through the tps. will have to check the pipe sensor. it would still be interesting to see what kind of map the autotune would come up with. so can you prove details on how you checked the sensor? step by step? thanks

Have 09 Assault, single exhaust, airflow kit, slp clutching, PCV, auto tune. Also running my (h82luz Performance) power valve/cylinder mods and slp map for 0-3000. The slp map did not make much sense too me but I loaded it anyway. There was not an AFR table so they must not use the auto tune. I set my own AFRs in the auto-tune and it pulls really freakin hard now. I have not yet checked my trim table to see what corrections it made to the SLP map. Maybe tomorrow I'll take a look.

SLP exhaust that is..

thanks mentzel, i would really like to know what kind of changes it made. if you feel like it, pm it to me and i will compare directly. i'm really liking the autotune idea...

Have you called SLP and talked to they guys there about your issues? They spend a considerable amount of time calibrating their packages so I'm assuming that, even from sled to sled, the variation in performance should be minimal.

I'll be running my Stage 3 stuff in a day so I'll check where my AFR's are at with that map and compare them with where I have been running for the last 3 years or so.

If you're going to play with an Autotune, make sure sure have the LCD or a good AFR gauge and just spend a lot of time watching and/or recording readings to get a feel of what is going on before creating new maps.

maybe go here to get a feel for what others have done:

no, i haven't called slp yet. was planning on it but wanted to see what people had to say here. i have a pretty good idea what they will say but i wanted to at least see if they have a specific map for the pipe and head (12.5:1) for 0-3000 feet.

I tend to disagree. If one little thing is different on your setup from what SLP tested, then the map they provide is useless. It might be close but... And don't bother with the LCD display.

The auto tune instructions have pretty good baseline AFR numbers to steer you in the right direction. SLP provided none; I'm not going to call them every time I make a small change to my set-up. After building my own AFR table, I did not spend any riding time screwing with it, which was great. Obviously start on the rich end for your AFRs and work your way leaner. I also considered leaving the o2 sensor in and running the auto tune all the time. However if it malfunctions you are hosed. (and they will malfunction at some point). The good thing is you can add a switch to toggle between auto-tune and your base map. The auto tune is really a tool intended to help calibrate your base map. Check out this clip, it will answer some questions. I will be glad to share any of my maps and AFR tables. However they will be just as useless as SLPs if your setup or riding conditions are not exact same.

thanks, good info. that's was the direction i was thinking of trying.
