it runs a ton smoother than the e6k that came out. i redid the harness, new coils, and a bunch of other little stuff getting realy for sevenstock

 

Kinda puts a damper on the misconception that fuel injector resolution doesn't matter, eh? I noticed the same thing going from the Wolf3D V3 to the V4.

How are you running the coils?

 

I'd bet since there is a real timing split now, it's also helping with the smoothness. Or that is if you're running a split on your FC coils or not?

That's cool that my old harness went to a good home

 

Glad the car is running smooth now. We put the microtech on (used to run the links system from Pettit) and all I can say is boy what a difference. The dash display is really nice as you can display whatever functions you want without taking your eyes off the road.

 

bermuda20b> any pics of your setup?
what display are yuou talking about with the microtech?

matt

 

yeah i wasnt expecting that much of a difference, but it did in a good way.
i used the ls1 coils and they have the ignitior built in so the wires from the e11 go right into em.

Kudos to you. Can't wait to see it next weekend. One of these years I might be able to drive mine down. Probably after they ban internal combustion engines

 

What kind of split, if any?

 

now,

What pics are you looking for? I have the dash display unit...works very well.

 

That's awesome. We aren't too far away from lighting off my rebirthed 20B FC. Going a different route though. I am using the stock Cosmo harnesses (Engine and Dash) along with all of the goodies from a front clip. The Cosmo ECU has been reprogrammed to remove the boost, speed, and Rev limiters. We will see. If this doesn't work, however, I'm going MicroTech. Here is the dash display:

 

right now i'm gonna run 10degrees across the board, later it will have spots with less split but right now i dont have the time

mike

 

it should work my friend was able to get a stock ecu 20b to run in his b2600, it idles so smooth you can put a glass of water on it and watch it not ripple

mike

 

Holy crap! Now I know what to aim for.

 

yah its truely a sight to behold

The difference is sequential fuel injection. 1.48ms at idle is 1.48ms at idle is 1.48ms at idle.

LOL, nice try. If your idle requirements are 1.48ms, and the EMS is only capable of 0.07ms resolution for example, then you need to choose between 1.47 and 1.54ms.

SFI doesn't make any difference at higher rpm's, which is what most RX-7 performance people care about. Go ahead, run the numbers, and you will see that within the powerband there is no time for any amount of significant adhesion.

 

Is this Brandon or Rolo posting?

 

It sure makes a big difference at idle though!

 

it seems to want a lot less fuel at idle and lower speeds than the e6k.

mike

 

who dosent want a good idle tho??

the microtech resoultion is .04 adjustable and .01 on interpolation,

 

OK, since we have since learned from the resolution-challenged Microtech Jihid that your smoother-running engine is due to SFI rather than the better resolution of the E11, please tell us what kind of SFI phasing you are running to achieve those great results.

 

Hahahah you kill me, man! Seriously, 10 points to you! I'm going to have to steal that one!

i'm using the injector phasing that came in the ecu. its fully mappable but we dont really even know where to start on that.

my car was tuned on the back of the trailer (long story), for about an hour. it starts hot or cold without touching the pedals, and it runs like stock oem hot or cold. and gets 18mpg on the freeway, so i'm thrilled with the e11, now

mike

 

Hmm, I never would have guessed that prior to asking my question (lol). (back to ignorant mode) I don't understand how you could possibly get the engine running so well prior to setting your SFI phasing. I know it can't be the injector resolution (lol). It must be that Haltech is so great that they set the SFI phasing for you because they consulted with Miss Cleo who told them that particular EMS unit was going on a 20B.

 

Really, injector phasing (the time, in terms of crankshaft degrees, at which the injector fires) isn't horribly sensitive at low RPM. At a 1000 RPM idle, you've got 60 ms between TDC events. That's a really big target at which to shoot. It only gets useful to tune at high RPMs (e.g. 7000 RPM has 8.5ms between TDC events, 6.667 at 9000 RPM). It's more the fact that the injector is firing sequentially that matters, IMO. Then again, I could be wrong.
