I take it your referring to one of these ? https://www.summitracing.com/parts/hly- ... 2731186257

It sounds like your pump voltage is set too high. You should be able to reduce it so you get no fuel pressure at key on if you wanted to.

I'm not sure what your asking ?

Well that obviously has nothing to do with the tps.

You obviously need more crank pw when hot.
Go kick up the crank pw at operating temp by 35%

even with the tps unplugged it would still start up

only possibility is that youve closed it too far and it cant get enough air

Thats just a stock car it should run like stock.

Make sure your throttle stop is set correctly.

Read the idle air and dashpot write ups.

That's dashpot, info is on the homepage.

Sounds like you have some issues going on as that's not feasible.

yeah you will need to swap the file back and forth.

No, crank iscdc is only during cranking and key off, soon as it fires off it goes in to idle which is derived from idle air.

What all do you have done ?

No idea, it works fine here. I pinged all the servers and everything seems fine. Might be jumping servers and you got caught in the middle?

Try reloading the page and see what you get.

I changed the input to FN810 for delta-n so I don't have to update it each time I change idle rpm and as a bonus it'll chase the rpm adders.

These are the two equations already in the code.

NOTE: //dsdrpm [50] *16 == 800 rpm. rpm [3200] /4 == 800 rpm.

OPTION A

Code: Select all

4ddd: 11,18             clrb  R18            R18 = 0;
4ddf: b3,72,e6,19       ldb   R19,[R72+e6]   R19 = DSDRPM;
4de3: 08,02,18          shrw  R18,2          R18 = R18 / 4;
4de6: 48,18,ae,18       sb3w  R18,Rae,R18    R18 = N_RPM - R18;

--------------------------------------------------------------------------
OPTION B

Code: Select all

505a: af,72,e6,30       ldzbw R30,[R72+e6]   temp6l = (uns)DSDRPM;
505e: 09,06,30          shlw  R30,6          temp6l *= 40; // 40 hex== *64 decimal
5061: 48,30,ae,30       sb3w  R30,Rae,R30    temp6l = N_RPM - temp6l;

--------------------------------------------------------------------------
Option B is what I'm currently using.

Neither of the two options have signed variables so what would be the easiest way to make it roll over and actually be a signed equation?
