Hi-Res code = ohmymotherfuckinggodamazing
 

I cant believe I didnt convert sooner.....The thing idles 460's perfectly at like 15.0 afr and the o2 gauge stays almost dead nuts on all the time instead of jumping around like usual. :bowdown:

10G? Congrats, having any random misses?

Thanks, 10g and nothing so far. The thing seriously sounds as clean as stock.

Hi-res is the best thing that ever happened to MSNSE. Instead of idling 550s at 11.8:1 I can now Idle at 13-13.5:1.

damnit ... when i tried going to highres the thing acted like a little bitch so i gave up and went back to 029v, but i just cant get it to idle well enough for me, maybe ill give it another shot sometime this weekend.

btw, did you install the cap and if so how much uf?

I didnt make any hardware changes for it....Im just using the 3.57 board. What is the cap needed for?

You don't need it if you're not having issues. It is recommended to eliminate tach spikes with the hi-res code though. It is also good for anyone having any sort of weird tach reading just because :)

maybe i should upgrade this weekend. i keep putting it off.....dunno why.


d/ling firmware now. i still have 10e here on my machine.

Maybe you should stop triple posting Scott and just man up and isntall it. Then after you test it install it on my megasquirt.

+1 that is about where my idle mixture is at with 550cc RX-7 injectors and hi-res.

Can someone tell my dumb ass how I can tell what res im running and how I can get the hi-res if I dont have it?

If your injector pulsewidth gauge shows "1.7" instead of "1.745", you aren't running HiRes.

also: If you haven't installed HiRes, you're not running HiRes.

The links for the code/installer are in there along with all the info on it.

Thanks fellas.

whats the big deal about hi res? can you start with the same .msq? use the same megatune?

Use the same .msq, same megatune, same MLV.

The main benefit (as explained to me by Jerry) is that the HR code can add and subtract fuel in smaller increments than the regular code.

yes. the advtanage is the PW.

like koto said above. you hi-res removes a few things form teh sandard extra code to be able to control injectors to the .000ms. this gives you tons of extra control.

for example, i have yet to install it. i idle at 1.7. sometimes it fights between 1.7 and 1.8, this causes a slightly lumpy idle. When I give it the ability to idle at 1.758, it should be much smoooooother.

this is also great for larger injectors when the difference between 1.7 and 1.8 is a whole lot of fuel.

alright, so i just went out and did the upgrade. I also installed my 10000uF cap for my cops. I had to lean my map throughout, but all in all it idles smoother and it seems to drive smoother. for example, with my 6-puck disc im still a tad rough from a get go, seems that issue is gone, its so much smoother into speed that im much better at much launches.

cool deal, i downloaded it, need to burn the firmware now i guess

What are the downsides to Hi-Res on a 2.2 board? It mentioned in the docs I read no flyback control, but I assume since flyback is an external board for the 2.2 that wouldn't apply to me anyway.. I don't plan on using low-z injectors anytime soon but am very interested in attempting hi-res. Any other functions or I/Os removed with this code?
