I figured I'd make another thread on this subject after I know software/hardware changes pretty often.

Ok. I have a stock LS, I just finished my turbo kit install, got it to idle and everything. I have a SC34 turbo. Want 300 hp.

I need to know what people are using now a days for engine management. And I don't want to spend $600 for hondata.

I have a chipped P72 ecu.

Also, I need to know what Map sensor I could buy that is a plug and play thing.

Thanks

 

crome

 

s100b is 1/3rd of that price.

 

crome = free
crome pro = $150
motorolla map sensor = $20 shipped

Get the map sensor from here......

http://www.digi-key.com part number MPX4250AP-ND

GL.

 

Thanks for the link to the map sensor, I'm about to order it.
Please bear with me, I have NO knowledge AT ALL about ecu tuneing. Every time I search for Chrome all I get is people talking about basemaps and similar stuff like that... I have NO idea what kind of HARDWARE I need. I don't think software will matter because I'm takeing it to have it tuned.

Here is my ecu. Could you please tell me if this looks right and also if there is anymore hardware i will need to run something like Crome pro.

Apparently, for use of an external rom, I need...

"The provision for an external ROM was made in the board design, and it can be activated by adding a 74 HC373, a resistor, two capacitors, J1 and a socket for the ROM itself. <- This mostly refers to the USDM ECU's. I have not seen evidence otherwise for JDM as most already have external ROM's present. Not sure for EDM ."

How do i tell if the modded ecu I have hasw all of that stuff done to it?

 

i personally would go with hondata setup, either s100-s200-s300

 

Is hondata its own unit? Meaning will I have to have a chipped ecu or is the Hondata going to be everything?

 

I just need this to be ready to tune fast. I have the car running!!

 

Do it right the first time. It saves money. Dont do crome, neptune,uberdata. Go with hondata. Either buy a new s100b or a used s200 or s300. I bought a used s200b for $300. It is also in fairly good condition.

 

you can get a whole hondata setup for like 500

it is its own unit so the ecu will habve to be socketed and chipped.

 

first off... whoever is going to tune your ecu will be able to tell you what they prefer or want you to have... if they can tune crome then make sure they can get the chip if not get one yourself.... and you wont have to buy anything.

if they want hondata ask the tuner what hondata they recommend

if they want neptune get neptune

etc etc etc

Thats probably the best idea, I'm going to contact them and ask them what I need and what they reccomend.

 

To sort out some of your confusion, crome/neptune/hondata all require the basic chipping stuff (resistor, capacitors, jumper, the small chip, 28pin socket). They all use the stock ecu, and if that is the picture of your P72, its best set up for crome atm, but will work with neptune or hondata.

With crome, you find a tuner, put in a basemap, hook ecu to laptop, and datalog. You'll usually want a dyno to test it on, but you're set atm for pretty much any tuner.

BTW don't run the car with large injectors and just the stock ecu tune. You will dump too much gas into the cylinders, and wash out the rings (no ring seal, tons of blowby, etc).

I am going to sound like a dick but who cares

are you ****** retarded? Neptune is a very good.......

Dont get me wrong though I know the person who owns Hondata and I will stand behind it but I would never tell anyone not to run neptune

 

No one was catching my point that I was trying to get across.

I was saying spend the money on a decent engine management unit.
Hondata is a stand alone system.

Neptune,crome,uberdata you can get mostly for free.

Thats all I was trying to get across

Sorry to get people mad at me, and start a discusion fight.

 

last time I checked Neptune wasnt free and Hondata wasnt a stand alone

 

I just told you I did not want to start anything. You just started something. With all the name calling.

I thought neptune was free.

I know crome pro is about $150

The regular crome is free.

Uberdata is free.

Now on to the hondata situation.

Why is hondata not considered to be a stand alone engine management system?

It has all the functions and things that a standalone has.

What makes it not a standalone?

 

Hondata is not a Stand alone because it is a chip and uses the factory ECU... here are some examples of why it is not a stand alone

* It requires the factory ECU or parts of the factory ECU to operate.
* It works in conjunction with the factory ECU, it does not replace it.
* It has a secondary box attached to the factory ECU

A true stand alone is like a Motec, Apexi Power FC, Autronic and so on. They use a whole different ECU and do not use anything from the factory ECU.

 

Thanks for the information.

So inorder for a system to meet the requirements of a standalone engine management system it has to use a whole differnt unit. Nothing to do with the factory ecu right.

I'd like to know as well. A piggyback engine management system lets the ECU do its job and both modifies the incoming and outgoing signals. Hondata and the like simply modify the registers that the OEM microprocessor uses to make its calculations. The OEM Honda ECU is a standalone engine management system, so I can't see why Hondata isn't as well.

I think the discrepancy is just in the nomenclature. According to your definition, anything that retains the OEM ECU isn't "standalone."

Yes, that is MY p72 itself. If I'm set up for my tuner as is right now, thats what I needed to know. Awesome

Yeah I noticed with the injector thing. I ran it for about 10 mins total and I pulled the plugs and its crazy rich lol. Could I have actually damaged anythign by doing that?

Thanks for all of the input

 

Just to get things cleared up. Can YOU use crome,neptune,uberdata,crome pro on an obd2 ecu or do you have to switch to a obd1 like I had to do with my hondata
