Ecu question

[NAiL05]

Why would he want to run a p28 if hes already boosting a non vtec....

[John Conner18]

why run a p28

But a p06 can be converted to a p28 vtec ecu easily for say if you ever do an h22 swap or the h22 head frankenstien g22 thing

not to sound like a ass, we are all hear to learn

at first i plan on only running say 5psi or so, or at least as low as i can get my chinese 16g to go, dang this tuning takes alot of research and is getting confusing

but our accords Saturated or Peak & Hold Injectors? ive been looking around on honda tech but no accord info so far, i found out how to convert if nessisary but i dunno if i need to or not? any pointers?thanks guys

The peak and hold verses saturated always gets me to.
But for an accord it's a non issue a 90-93 accord has a resistor box so you don't need to convert anything for commonly used dsm 450cc injectors. you just have widen out the seals with a dremel tool to fit the larger injectors then just install them the same as stock , their is also a little plastic tab on the inside of the stock honda plugs that you just have to trim off with a razor knife but it's so simple you don't really even remember having to do it after your done.

You have to get the car tuned for the larger injectors with a chipped ecu crome uberdata, or safc vafc one of them things that can control you injectors. if you try to istall them and just run stock yor car will run really rich or not at all. I'd say it would have a hard time idling and would probably foul the plugs really quick.

but to answer your question cb7’s have peak and hold injectors. thats low impeadence.

Does anyone know how to convert from peak&hold to saturated? A lot of rx-7s have 550s but their usaully saturated. If you guy ever go to a junkyard you'll notice a lot of rx-7s untouched with the injectors still in them.

Dsm's are always picked clean though.

thats sweet thank you man, about the seals though where do i get them, and what kinda of car are they off of, i presume they are different then accord ones so those wont work, any sugestions, and about that plastic piece i may have to trim off, got any pictures? thanks

p06/p28 here i come along with o2 wideband and safc 2 for own tuning

Heres a good write up on it from homemadeturbo.com

ive already seen it but thanks for the help on refinding the link, it will help anyone else with this question

[John Conner18]

this question came up today at school while duscussing turbo/ecu

if i am going to need to use a safc 2 too tune, why am i worried about getting an ecu, i read before this that i still need one, if the safc2 over rides the stock ecu whats the point, other then having a basemap?

btw i will be turning with an safc2 and aem(prolly) wideband o2

edit: ok again i looked back threw my post and found an awnser, hmm but r33 said i need to have it tuned anyways even with a p06 chiped from mrx, why not just skip the ecu and tune it myself safc2, and wideband i know people that have done this before locally

[d112crzy]

because a safc will only get you so far before you blow up.

tuning a chipped ecu is pretty damn comparable to having a full standalone. well, as far as being able to individually tune fuel and ignition maps goes.

so in order for me to take advantige of the ecu and tune it myself i am going to need a wideband o2, and a laptop to plug into the ecu and use uberdata i presume, i dont have a laptop and sure id love one but i dont want to have to buy one now for tuning, and i presume a safc2 wont let me tune my ecu stuff correct? thanks for the help

what can i do with uberdata that i cant do with safc2, i presume adjust timing, cant i adjust the distrubtor for that

[d112crzy]

you cant adjust a CERTAIN rpm and or vac section. with safc, you either richen it up or you lean it out. there really isnt any choosing with it. same thing goes with the dizzy timing, you can only adjust for the whole rpm, not at single points.

and you dont need a laptop. I dont have a laptop, i only have a wb and a chip burner.

do w/e you want. your money, your time, your choice.

[Cronis]

Yeah their are a lot of things you need to tune a chipped ecu.

A laptop for data logging a wideband 02 sensor and a chip burner or a rom emulator called an ostrich that you can find at moates.net.

the ostrich plugs into the chip socket on the chipped ecu and then connects to yourlaptop for realtime tuning you can drive around datalogging and change things as you drive from your laptop. uhh if you had one.

Ecu chipping and tuning is invovled and takes time and lots of research to understand. no to mention all the things you need to do it cost money.

the only part thats free is uberdata the program it's self.

Crome is newer and has more support right now but for the full version that you can datalog with it costs 150 bucks.


But it is worth it to take the time and learn how to tune. and get the things you need to do it. Because with a chipped ecu and a tuned rom it is setup perfect for your car at all rps all types of load in every gear.
asuming it's done right.

The safc can't tune your timing at all in fact from what i've heard from people at pgmfi it actually advances timing. advanced timing is not goof for a turboed engine. that causes detonation. detonation is what blows your motor.

But if your only running a few psi and not making a lot of extra power from the turbo a few degrees of retard at the distributer some larger injectors like dsm 450s will work okay.

I mean people were running cars like that a lot back in the 90s before anyone knew how to even chip a stock ecu and no rom editing programs were out.

I think for now you can just keep you goals small and just us the safc. to run a few psi the go for more later on when youve learn more about the process of tuning and have the things you need to do it with.

there is one other thing you could do to skip a lot of this and probably be a lot happier and save money in the long run. Just find a tuner that lives near you and just have them do it.

the tuner will have all the equipment he needs all you will need to do is have the car running right. it's all up to you what you want to do but those are pretty much your options.


Hey D112cry. Do you have any chipped ecus for sale? I need one.

*L* Ive tore up two p06's trying to do it myself so I'm just gonna buy one.
