The Journey 89 turbo'ed-----89T

[Robs89LXi]

Well, I also have the luxury of not having to use my 3G as my daily driver. It is a lot easier to experiment and take your time learning when you don't have to depend on your toy for daily transportation. Since I do though, then yes, I would much rather learn how whatever system I use works, than just blindly depending on someone else. That way, even if you get to a point where you will need help, at least you have a much better idea of what is going on. Long term, you are a lot better off as well, especially if you constantly update your car.

Just a little tag on here too:
I would sure hope that everyone, and anyone who does go boost, or upgrade engine management, will share what they have done on this forum. Thanks.

Fuck hondata. I think that some SDS systems are pretty good, as are megasquirt etc... i dont know much about neptune though. I prefer to run open loop all the time (and i do, lol). If your good enough a tuner, running openloop all the time can actually increase your gas mileage out of boost and simplify tuning (at least i think so)

[89T]

tell us how you really feel.
i took this right out of the book.
closed loop defines the engine operation where the fueling level is calculated and corrected by the ecu from the o2 sensor.when the o2 sensor emits a voltage signal above .45 volts due to a rich mixture ,the ECU reduces the fueling level by reducing the pulse width of the injector.
open loop defines the engine operation where the fueling level is calculated by the ECU with only the input signals from the tps, coolant, and/or air charge temp,and from the map sensor.
from that i would expect increased fuel milage in closed loop during normal driving, and open loop under lead-foot conditions.

Some of those systems even have an 'autotune' function, you can set the a/f value to what you want, and it will figure out the pulsewidth itself. (obviously with a wideband) I think neptune has that. I guess most of those setups don't tune the ignition though.. I know of one system that used a g sensor, presumably to alter ignition timing on the fly to determine maximum brake torque like a dyno, but I don't know about that anymore. Cybernation has some interesting things out there for the k20 also. The 'guardian'

What's wrong with the s300? You just don't like the price tag?

The only reason why cars don't run in closed loop under full throttle is they don't come with a wideband o2. Some cars do now though. The most popular wideband sensor used by the aftermarket is a vw part, but you already know that..

Actually, as far as open loop all the time, I know why you said that, you just want to run at 15-15.5:1 under cruise instead of 14.7, with a little more timing. You can still do that in closed loop, you just have to set it to do that in your program with the wideband.

Now, does anyone know why running leaner than stoichiometric can give you better mpg? it's not an obvious, easy answer..

[89T]

I would have to guess,that is where an engine makes the most power..
11- 12;1 range.
althogh I could be wrong...
I thought i would give it try...

[AccordEpicenter]

ehh i think the hondata guys are snotty, and all that shyt is mad expensive... And yes that is why id like to run open loop all the time

[Kabuki]

I'm telling you, guys... check out PGMFI.org. We can do anything we want with the stock Honda ECUs. You may need to use one from a Civic or Integra, but the wiring is nearly Identical. Crome Pro also has the Autotune feature, and works very well coupled with an Ostrich real-time programming/updating circuit, and a wide-band oxygen sensor meter. You can tune on a dyno, or on the street. And this stuff is all made by small companies and supported by a huge DIY community with tons of experience. Don't give your money to ZDyne, Hondata, AEM, or the like. They make plenty, and don't have the kind of support infrastructure they should.

[Accordtheory]

I think the price goes like this: ostrich+ cromePro<neptune rtp<hondata s300<aem ems. I think for n/a, the ostrich+uberdata would be ok. I need to check up on the neptune setup though, I don't even know if it's out yet..I think it was supposed to be though..

[Accordtheory]

hopefully get the accord done cause iv dragged it out way to long granted the amount of money spent on it is a rediculous amount no matter how you look at it.

You're not alone with that sentiment..shit, if I would have known how much I'd spend on this stupid car before I did anything, I would have just sold it..

96+ civic hatch: No soul, but no weight either, perfect turbo b series car.

I've been talking to this other guy named Hugues here's his cardomain site>> He wrote in french it just so happens i know french. http://lowrider.cardomain.com/ride/771359/1 He is running Megasquirt and he gots his up and running. I'm tring to get him to come on the site. I know gf-r-g88 on here talked to him too. I'll talk to him some more to see how he likes it.

[89T]

check this out.
a friend of mine just got neptuned.
he was rollin the blue box,dynoed with the blitz power meter(like the g-tech)
he had a previous best of 234hp
put the p28+neptune on a street tune and came up with 278hp on his power meter. thats 44 hp difference!
he didn't make any other changes to his car.

i cant wait for dyno #'s.

[89T]

speaking of stand alone's...
F22 dizzy...
wire diagrams with and without internal coil?
even a shop drawing will work.
anyone have one?
(theres another new post on page 2)

[89T]

I could imagine...
3 set's of tires a year.

[89T]

http://cgi.ebay.com/ebaymotors/SKUNK...QQcmdZViewItem
plus a 70mm throttle body...
550 injectors, or shall i say screw it and go 1000cc injectors.
i am going stand alone so it would'nt be a problem either way.

[89T]

anyone?

[Bglad420]

Go for it....Hey PM me I wanna ask you a few Q's about your Turbo set up, mainly your dizzy, and fuel management.

[Accordtheory]

Why not just get the aebs? Probably just as good, like within 1hp, and about $150, instead of $230. The S2 is a 'direct bolt on', and smog legal, but not to the a20 anyway, so who cares.. But if you like the skunk2 better, go for it.

[3G Jester]

no b series mannifold is a direct bolt on. they all need moddification.
if you wanna be that ballin and get the S2 intake manny--go for it. and as far as the carb legal thing.....yeah it may not be carb legal on the a20 but they dont know that. if forsome reason someone is looking under his hood, and htey see the sticker...chances are they will say alright. not deffinate but its a possibility.

[AccordEpicenter]

aebs typhoon>skunk2 intake mani. Its cheaper too. Im thinking about getting a 65-70mm tb too, they are just damn expensive!

[w00tw00t111]

Thanks for asking this 89turbo b/c I was wondering the same thing!

[89T]

aebs typhoon>skunk2 intake mani. Its cheaper too. Im thinking about getting a 65-70mm tb too, they are just damn expensive!

why the aebs typhoon over the skunk2?

i figure why go in it half way when you can suprise the shit out of people when you open the hood of an old ass accord.
You for one should know the look, when you pull away!

it's just like anything else, you'r buying the name.

for those that think i am ballin; this is a hobby for me, It keep's me out of the bars, off drugs, gives me something to build (I do the fab work myself) and i would be damb'ed if i did'nt like to go fast!

you'r right the tb's arent cheap. I have 70mm from a 5.0 mustang that i'm going to try and fit. I need the intake first to see what modifications will need to be done, or if i need to make an adaptor plate.
either way i'll make it work.
