During the past 2 years I have spent many dead presidents adding bolt ons to my car and have not been able to realise the full potential they are capable of by running a stock ECU and Piggyback fuel controller. To get the full HP I feel the new motor is capable of (Spoon 12.3:1 Longblock) I know I have to do some serious tuning, and it cant be done with a Field VTEC Controller.
I have spent many hours researching the differences between Uberdata, Crome, and Hondata. Most of the main differences are in the GUI interface. The ECU prep work is almost identical, using the same components and real time datalogging uses almost the same components as a Hondata s100 system. For those of you who are not scared of DIY and want to tune your R (or any honda), I have ordered all components necessary for going down this road. This includes a P-28 and Harness adapter, datalogging hardware, ZIF socket chipping hardware, reflashable EEPROMS, and have located all base maps including Stock, Mugen and Skunk. I will begin posting all info/problems I run across, pics, and any sources which may be useful. I weighed the costs of Hondata VS. a DIY and found for 1/4th of the hardware cost and the same amount of dyno time required, I expect the same results (given the skill of the tuner in any case).

Running total so far:327.00
Virgin P28 Sourced from salvage yard : 115$ shipped
OBD1-OBD2b adapter 87.00 shipped (JDMSHIT)
Chipping hardware + 2 eeproms : 21$
Datalogging hardware (serial Interface) : 19$
EEPROM Burner (USB Interface and software): 85$
Datalogging software : Free
EEPROM burn software (comes with burner): FREE
Base Fuel Maps : Free
ECU Mod Software: FREE

I will continue to update this post with pics and how to articles, of which alot are available on the net, just not all in one place

 

i never really heard of uberdata til recently. is it like hondata?
what is crome? is crome like hondata?

 

Keep us informed.
Alternative options and information are always a good thing.

There are a couple HUGE threads in the FI forum on uberdata. also: http://www.ecimulti.org/uberdata/

 

sweet, i will read em thanks. Both Uber and Crome are like hondata... just free

 

this thread intrigues me because i was thinking of having willis on this board tune my car with uberdata

I've been suggesting Uberdata, and will be running it myself soon.

There's enough work behind it that the support shouldn't be a problem.

 

Just wondering if you were also planning on buying a wide-band O2? I think that should be part of your list if you plan to do your own tuning. No point to datalogging without that.

 

Yes, along with a romburner, I will be buying a wideband 02 (going in with some friends to share the cost)

the PLX works great, i use that one too .

But CHrome and Uberdata seem to be getting great reviews, and best of all its free.

 

nice, interested to see your results...

 

Here is an update on the project:
to answer a few questions, yes i will be using a wideband, Tweak, you said you were going in with some buddies to get one. Understand that you dont need to use a 250$ honda wideband, or a 500$ wideband kit. The wideband that alot of uber users have been using is actually a 4 wire VW unit available for 25$. This paired with the PLX controller which has to be wired into the ECU harness adapter (which is cake).
here is a link for a good, cheap wideband: https://www.parts.com/shopping...13799
I ordered all the nessesary chipping components and a rom burner from moates.net. He has kick *** service and received all my materials in less than a week.
I did a little research online via the salvage yard database and came up with a source for a P28 from a 92 Si. I ordered the ECU and if you can beleive it, Mr. Brown lost the freakin package. The shipper did a tracer and got nothing back. They filed a claim and sent a new package which i received 4 days later (today). I opened the package and it had the telltale paint stick marking of a salvage yard. I opened it up, which should give me this picture:
But instead i see this:
guess what that would be... yes, a chipped ECU right from the junkyard. Now to desolder the chip, add my ziff socket and pull the program off the chip with my burner.
Update to follow...

cool, I wonder what program it is?

DIY ECU tuning kicks *** - thanks for the update...

(who hopes to do this someday)

Those sockets were orginally designed so honda could do updates to the ecu if needed. You more than likely got an ecu that had been updated. So yeah... chipped by honda

big to Ubderata. My 94 Civic Si and my room mates boosted ITR both run Uberdata

 

uberdata 1.66 im runnin it with no problems thus far

datalogging is possible now, obd1 hondata is finished

 

Euclid, I have not been able to get the correct version of Uber with the datalogging tab in the program working. CAn you email me the zip file you have that works?

 

I will be using this when I get my motor in. DIY kicks ***!

 

Email sent...should be everything you need for the datalogging. Just have to either create a new basemap or import from an older version. Unfortulately, you can't just open an old bin.

 

How are you guys connecting the ECU to the laptop? Serial? How do you put the serial port on and where? I think I need to new version also. Can you send it to charich@***.net ?Thanks

 

this is great....

can you post sites of where you got some of the components? particularly the eeprom burner...

thanks,

YV

The LSU4 VW O2 sensor is actually a 6 wire sensor but is considerably cheaper ($25-$35). Techedge, PLX and Innovate LM-1 all use that same sensor.

 

tyhanks for making that clear, i have only read about it on the PLX site, but have not seen it yet. They actually sell an extension harness for directly plugging the sensor into the controller, so you only have to wire the coltroller on the ecu side (3 wires and a resistor on the ECU Harness O2 heater circuit).

Here is the link for this info right from the PLX site:

well, split's idea seems to be correct. I pulled the program off the chip and opened it in Uber. It has exactly the same low fuel map the stock p28 bin has, so i guess it was a honda chip... Thanks Honda for doing most of my work. I added my ziff and programmed a chip with a base map. Now to install the ECU, update to follow...

 

&lt;- patiently waiting for update
