Help me tune..

- Start date
Here are 2 maps I have used. The top one is what I put in 2 of Beau's cars running his kits on a P5 at 5psi. The bottom is mine at 8psi, they are the same, I just lowered the multiplier on the 1x16 column. I rather be safe then sorry. The base map is one Little Beavis gave me a while ago, I just took a little more out. I would just load the 8psi map and tune the fuel to 12.0 or less running 93 octane. My J&S doesn't go off at all even with the bad 91 octane they have out here. If you want to be more safe, just increase the -6's by 1 or so and maybe the multiplier by 1 or so. A few degree's too much out doesn't take that much power away. I even did a dyno with 101 octane and added up to 8 degree's and only found a few more HP, but as it got hot the J&S started to go off, so this isn't too conservative and you wouldn't feal the difference in a couple of degree's.
LinuxRacr told me that the timing was set a few degree's off what stock whould be, I don't know which way though. His tuner was having problem tuning the Haltech until he found that. It's all fixed and running good now.MPNick said:

I was talking about when linux had the MPI. He had #s in the -20 & under in the 8x16 alone with nothing in the 1x8 boost retard column. Could he have lowered the #s with #s in the 8x16 with #s in the 1x8? Yes, he could, but the stock mp3 ecu has timing advanced up to 63 at certain RPM ranges and he had the MPI set up a bunch of diff ways. But, each car is different and not all maps work with other cars. When measuring actual degrees of timing these cars like timing advanced in the low to mid 20s when in boost.

I never hit the limit of the MPI timing retard, so if you say it's -44 then subtract that from the max of 63 degree's for the MP3, you have 19 total degree's of timing. That's not a lot of timing, considering I am only taking out a total of 15 degree's off the stock timing.
I certainly agreee about each car being different, that's why people shouldn't want all these maps, all you need is a starter map you can tweak to your setup. And I do also agree with the "who needs a dyno" statement. I bet if mazdaspeed75 put his car on the dyno, he wouldn't get very much from tuning on it, since you did the road tune and that seems to be pretty damn close to what you need on a tune. I have only gotten maybe 5 more hp tuning on the dyno, so road tuning is the s*** and cheaper.
BTW..I changed the injection map to look alot like the one Timm posted in the first page...Altho it seemed that the AFs were OK as I built boost, but as full boost came on it would start going very lean...Not GOODDDD..so I tried to add some more area to the map and kick up the top right values a bit..Im going to try to get a nice right map that will pull OK so I can take a datalog and see what you guys can do with it..

That column should be 1's to start, then you can reduce the values as needed to fine tune when the switch comes on. I have a .15 and .25 where the TM comes on, then goes back to 1's. The .15 will only give a fraction of the fuel for that load. The TM comes on at that load area and doesn't need all that fuel, but does need it afterwards, so that's why it goes back to 1's
A datalog will help a lot. Tune the analog map to as much fuel as you can get out of the 4.98v, then add the rest via the xtra injectors.
OKOKOK Here is an update...Here are the current maps I am running..
Here are a few short data logs..

After my 4 hour ride from Charleston back to Clemson, my exhaust wa getting very loud..I havent had a chance to check yet, but it sound like I have a large exhaust leak in my downpipe area..The turbo is loud as s*** now haha I kinda like it..
Please help me out though, I am getting lean in high RPMs in boost and I don't really kn ow how to correctly alleviate the problem.

You may be leaning out up top because on the 1x16 column on the analog tab you don't have 1's, so you're only getting a fraction of the fuel through the stock injectors. I know you have xtra's adding the extra, but try to tune the stockers to the max, then add the xtra's. If you feal the switch coming on, trim it on the 1x16 in a couple of boxes, then make the rest 1's.
On the timing, you shouldn't need timing out in the 2nd column. I have all 0's in that column.
After looking at your logs, you need to richen it up when you come on boost, I see it leaning out and you are no way near the 4.98v mark, so you have plenty of room to add fuel through the stockers. Do one column at a time and do the analog first, then when you hit the 4.98 mark, use the xtra injectors, if needed.
It also looks like you're leaning out a little in the lower non boost area, you may want to make the 2nd column all 4's or so. Maybe a better log that has more non boost and more boost in it.
JDM---if you load his log, you'll get his map. He has a fuel cal of 0 and his switch is at .65, maybe a little low, but I don't know how his turbo spools.
KzA---does the switch ever come on before boost? You only want it to come on at like 1psi or so.

Another Datalog..At this time im working with JDM Sam via AIM..Let me say he's most helpful...thanks for looking through the thread guys
