A few weeks ago I purchased a Hondata S200 Unit with Hondata P28 ECU.

I went with Hondata because I thought my buildup would end with just some very high lift cams and somewhat high static compression.

I have never dealt with or have any experience with Hondata. Does that ECU come with base maps preloaded on it? If so, could I download a different base map on it without purchasing the other software through a dealer?

Reason why I ask is my induction system, as I was told, is very sensitive to humidity. I wanted a system that I can upload base maps to on the go.

Thank You for all your help in advance.

I don't know if the S200 ships with a base map. My Stage 4 did not; I got it about a year ago. You need a laptop and the "romulator" to program the ECU on the fly. You will need two seriel ports on the laptop to connect to the ECU, one for datalogging and one for the "romulator". You also need "Rom Editor" v3 to edit your rom tunes. If there is a way around this, I am not aware of it.

 

Hmm. Well Hondata has TONS of basemaps. Where did you order your's from?They should have chose one which closely resembles your build up.

I purchased mine from my buddy Kyle at KS-Motorsports. I'll have to call him and make sure he sent one with a good basemap, because I really want to get this thing started and broken in.

 

I woud imagine kyle sent out a good base map. As long as u knew your injector sizing and other basic stuff, kyle should have sent it out to you when u ordered the S200

 

Bob, in the package there are what looks to be EPROM chips, excuse me for my ignorance but what are those chips for? Do they have base maps loaded on to them?

 

The larger chip of the 2 will be your base map. Also you shoulda got the cd with the system (I did anyways and I also ordered it from Kyle) just pop that in and get the directions for the US OBD1 ecus and its really easy unless your ecu is already socketed then you just need to pop in the base map chip.

 

I'd run a stock ecu to break in the engine and then tune the motor with the hondata s200. remember, the base map is never meant to be for your motor, you have to get it dyno tuned. my buddy's and my car gain about 10whp from just 1 hour of dyno tuning. the basemap is only for temp. use.

 

I have hondata s100 w/ a basemap. How do i know whether or not it'll be adding enough fuel? Should i crank the fuel pressure way up on the first run? I dont want to run it lean on the dyno and blow it up on the first pull cuz the basemap is too lean.

very true, and that is what hondata advicates. but it just depends upon who makes your base map.

we didnt play with cam gears, just an hour of tuning by lawrence @ dsr

Im sure the basemaps that myself or DSR makes are much different than the ones you get from KSM....
The difference between tuners, and retailers.

I agree. I know people who's cars ran like crap with a basemap.

I got mine from a good tuner and the car started up with no problem at all. Even made a 250 mile trip at average 80mph to get tuned with no problems.

Hrm, I'd love to run the stock ECU during the break in, but I don't think it would work with high compression pistons, vtec killers, 440cc injectors, and itbs.

 

who did you get all your toda **** from?

maybe u can convince jeff @ ib to get a base map.

im pretty out of the loop on who is running toda d's right now.

everyone knows the p1 car, but it wasnt on hondata

who were u going to have it taked to anyway for hondata tuning? u might have to have it towed there to and have them do a basemap for idle then go from there.

but im still not that knowledgable when it comes to tuning, so i could be wrong on what it would take to make your car drive able relative to a base map

edit: u didnt answer my IM about my parts q.

 

You could use my Toda D tune as a basemap, but I am running a big TB, not ITB's, so I don't know how well it would work.

Yea for your setup, stock ecu will not work. Try to find a good base map and
break it in the motor w/ hondata. As soon as the engine is broken in, get it tuned.
It makes a HUGE difference after it's tuned.

Just FYI, not knocking on KSM, they got the best deal on Hondata and I personally
bought 2 S200s from them but their base map do not work well at all on my freshly
built engine. I know its for temp. use but I use a p28 skunk2 chip to break in my motor. Maybe you can try sgT, hear a lot of good stories about him.

Would be way off.
With KS, like most people, he just uses the hondata easy setup method which
imo doesnt work that well, i used to always end up modifying a lot more. Now
I have my own base maps.

 

Hondata is sold guys. Picking up an AEM EMS soon. Hopefully I can play with the EMS and try to get it to idle. Unlike Hondata, I have a little tuning/******* around experience with the AEM. Thanks for all the help guys.

As for who is tuning it? Jack@P1. Hell if I had it my way and I had an endless supply of money, I'd pay Jack and Steve to tune my car. Steve is too far.

 

if you couldnt get it with the hondata, doubt you'll have much luck with the aem.

 

i have only played with aem once, hondata is way easier.

good luck though.

We'll see. I just called Steve today to see if he could make me a base map so I can just break the damn thing in. My EMS is ordered but won't be in. At least with the EMS, we can play with alot of things I can't do right now with the Hondata. It's not fully unlocked so I can't edit anything. (Yes, it's my own ******* fault. What was I thinking?)

I'm actually very familiar with the EMS and got my buddy's Turbo'ed ITR to idle with them. So I don't think this will be impossible.
