I am setting up a new basemap, and i want to be completely clear. It is too slow going on the actual uberdata forums, but here is my question. when setting your fuel modifiers, the suggested value for 450cc injectors is 53.333ect. In the instructions i have it says that (tps, cold enrich, main enrich = 240/injector size*100) That is how you arrive at the 53.333 figure. Okay, so does that mean that you set the tps enrich and the main and the col settings all to 53.333? The original basemap i created for some reason left the tps enrich at 100, and then changed the cold and main to 58.

 

basically i just need to know if all 3 modifyers should be the same, or does one have to be at 100? I think this is why my car is not running as well as it could be/

 

Most people run just TPS and Main enrish to like 60 for 450cc injecotrs. You can leave the cold enrich alone since that is only when starting up anyway. Make sure to check off enable so it actually uses those values as well.

It really doesn't matter if you use this... It helps out with throttle response a little. and prevents it from pegging rich when you stomp on it

 

I went ahead and tried all 3 at 58 and when i started it i knew right away something wasn't right, it was all hesitating and everytime i gave it gas, smoke came out the exhaust.

 

I rarely even turn the fuel modifiers on ...

Most people do not as the issues that tend to come up while using them .

 

switch to crome

 

I run cold and tps enrich at 60 with my dsm 450's and the car runs flawlessly. I would really post this over in the uber forums though. Response may be slower, but they will know more about your problem.

why would i want to use crome?

 

I thought that chrome was for non obd people? I am going to try and run my setup without the fuel modifiers enabled. This isn't going to make my motor run lean by any chance is it. the modifiers only add fuel right...

 

this is nice.......i post a question about uberdata here and it gets locked........

buch of HT homo's for moderators

 

That sucks. This is as technical as it gets

 

You can just dial in the injectors and hit enable...

what do you mean by that?

 

You can play around with it, but 60 works alright with your injectors. Just fill in the boxes and hit enable. My bad.

 

Crome is cool but for boost you have to run the P30 base code...

 

I get that, but what boxes do you put 53 in. just the tps and the cold? and do you leave the main alone or what? what is it that you do. The instructions in the uber forum seem to me to sy that you set all 3 the same... But when i did that, my car ran like complete ***.

 

Honestly, I usually don't even mess with them. But 60 seems to work for most people. Try it without and see what happens.

set all 3 to 60? the tps enrich, cold enrich, and main enrich? that is my real question, do you change all 3 to the same..

Try this, seems to work for him. I honestly don't run the modifiers a lot.

 

I ran them once and didn't another time and I don't remember noticing a difference.

 

I never run the modifiers. They cause more problems than they are worth. I can never seem to keep things as consistent or make car's idle as nicely when they are enabled. Just some first hand experience.

im not running them now and i feel that my car is more than driveable. i dont remember if i had them enabled on my last setup either. ive heard they really dont do anything. for the injectors, just type in what your new size is gonna be and then make sure it says 240 for stock injectors below it. uberdata will automatically rescale everything for you.

 

If you think your car runs better with them off chances are you have them set wrong.

I'm running 1000cc injectors, and 24 is the number that is reccomneded by the calculation. If i dont have 24, and i have it off (leave enable unchecked) then the car leans out when i step on it and into the open loop transition.

Just use the calculation, and enable it with that, on all 3 at the same setting. Then make sure to use injector null time to relate the scaled fuel values to your injectors. That should take care of some part throttle woes. least it did for me!

Leaving it unchecked should cause your car to run richer when you step on the throttle. If its unchecked then it will dump in the normal 100% value when you go WOT. That is why you scale it down to 24% so it dumps in less fuel and doesn't cause you to bog with those huge injectors. Thats the way i see it anyways...

They have a new script or patch that lets you run P72 code now. It was a long time ago when I upgraded my version of Crome from the one that would only do the boost on P30. But I patched it or something and now I can open up a P72 map and do the boost table adjustment no problems. I dont know if the actual programming code is still P30 based or P72 based though. I just know that now I can open up a P72 and do the boost ish to it.
