I know you can't boost like that, but I wouldn't put that in the table. What do you think? |
after reviewing my current modified version of curlys im going to switch to hustlers, looks a little smoother for a street car, but you didnt leave yourself a big 15.x area for milage did you?

That was adapted from one of Scott's maps I believe, so you can talk to him about the benefits. I would argue that it's smoother, but I'll take a little jerkyness going into cruise if it means I get to save a couple mpgs on the way to the track. Again, not a DD, so your choice may vary.

There isn't much in regard to "smoothness", drive-ability is achieved in the VE and spark tables. My numbers are based on output and several truths I discovered in the tuning process such as:

Use the MSPNP base map. Search for AFR target tables, they're the important ones. I think JP has some good ones. Keep the MSPNP spark table, aka: DON'T ------- TOUCH IT.
Then use VEAL and those AFR targets to tune your fuel table. It's usually fairly rough at first. |
For spark yes, follow his afr advice though. That's interesting about the 15.2, makes me wanna play around with mine. ABE! chop chop!

Just for you guys to laugh at me, i forgot the Mspnp base tune has overboost protection set to 1.5psi. doh :noob:
|
The important thing to remember in cruise is that you're trying to move the LPP based upon spark angle and fuel. The leaner you go, the more advance you need to hit LPP at the right spot in the crank/piston's cycle.
Sometimes I wonder if better fuel economy can be achieved on lower octane fuel because it "lights-off" faster. I also am fairly certain that stronger spark can help fuel economy too. |

Don't feel bad, I still can't get Jeff's car to run in boost at all.

not injecting fuel and cutting spark can do that :)

Sure. You don't need me to tell you this, see how the car drives. It should drive fine with that AFR table, so if it's bucking make spark or enrichment adjustments.

edit: if it doesnt like it i will switch back to the previous table till i can figure out the problem. |
alright so stupid question but why is there not much info about launch control? i kinda want to use it, i think.
