What up all !! i have some question which i need to know badly From where i belong Ecu tuning is Young and new i know the basics but still am in a learning state i have a few questions and need user coments


1)I want to connect my chipped ecu to my laptop with Ectune pro i know i need an emulator and data logging kit
but my question is Which emulator burner or what do i need to edit my maps live and save them u know what i mean what do i need

2)My Frnd had a jdm 1st gen obd0 b16 bone stock with a toyota ct26 turbo stock ecu just DSM 440cc injectors he used to run 5psi all day used to have knock but then using a higher octane fuel the knock would vanish i just wanted to know as he was on a stock ecu obviously no extra boost columns i assume then why do people on low boost stock setup chip their ecus when one can have low boost on a stock ecu to a limit?? what tables was he runing? which columns mostly on 5psi? and wht is the main purpose of using extra columns?6-10 columns?? sorry am new to boost

3) if am runing wot will the map be reading from the last columns?
thnx in advance
regards

#1 I have no idea.

#2 Not sure what kinda setup he had but it sounds pretty bad.. Any amount of psi added on a stock ecu is going to have issues. Unless he just had a FMU but even saying FMU makes me cringe its old technology that needs to go away much like an safc and a map bypass valve.

Not sure what tables, although if its a stock ecu its stock tables.

to answer #2 and #3 WOT tuning would be the last columns on the right usually its the last 3 columns from low rpm to high rpm. Taking an NA map and modifying it for boost you will simply add lines/columns in psi for in boost. you will have to add fuel and pull timing.

the # of columns you add can be as many or as little you want for granularity I think I saw some sample maps and they were in 1/2 psi increments... so fuel/ignition maps can get quite large if your target is lots of psi.

I think he probably got away with running 5psi is because a stock ECU will pull timing... I'm not sure how much but I would imagine when he was at 5psi and wot the engine would be pretty lean, but then again I don't know what A/F a b16 runs at wot with a stock ecu.

 

First option would be the Moates Demon. http://www.moates.net/demon-p-208.html

Second option would be a Moates Ostrich in conjunction with a Xtreme Hulog datalogging cable.

Your friend was using a stock ECU that was designed to run a boosted engine. There are no OBD1 Honda ECUs that are boost ready out of the box. That is why the boost columns have to be added.

As mentioned WOT is far right......depending on your manifold pressure. If you start to pull vacuum. (intake restriction) The trace/map will start reading back into those columns.

 

thnx ghost accord that helped alot but what if i use extra boost columns on as low as 5-6psi will the ecu still read from the stock columns? or will it read from the added boost columns?
thnx for the help so far ur post really helpd

and how do make an engine rev so hard i mean the sound of limiter of k20 is so fast as the h22 is slow can i somehow make the h22 rev limit fast? like a k20?

 

Yes it will still read from the stock columns.

The added boost columns are there so that your ECU can calculate for any +pressure in the manifold that a turbo will give you under boost. The Stock ECU and maps are designed for a naturally aspirated engine. Therefore the maps are really only based to go from vacuum (- pressure) to atmospheric pressure + a bit (sea level = 1013.25 mbar). So the stock maps are set to read 1035 mbar (0.5psi)

Whatever your MAP sensor is rated for is what you set your final boost column to. (Stock MAP will read up to 8-10 psi.) Probably more reliable to get one that will read 2-3bar (3039.75 mbar)


If you want to speed up the rate of your RPM (throttle response) you need to lighten up some rotating assembly components and or shorten your gears. A Light weight flywheel and an H2B trans would get you revving just as fast, if not faster, than a K20. However there isn't always the need to rev that fast if your engine has tq in the lower RPMs. The H22 has tq in the lower RPM. It doesn't really need to rev high to hit it's power band.

 

I was talking about the rev limiter why does the K rev limit Sound fast some1 told me that if u advance the ignition map @ your rev limit point then your rev limiter will be very fast

 

You should ask that person to explain it to you in more detail.

The rev limit is based more on the ability of the engine to maintain stability/reliability up to a certain RPM. It is based on the limits of the parts in the engine. I.E. the parts of the rotating assembly and the valve train. The rev limit (set in the ECU based on RPM) really doesn't have much to do with the advancing or retarding of the ignition timing. Sounds more like you are talking about knock or detonation/pre-ignition limits.

Honestly, I'm sorry. I have no idea what that some1 was trying to say to you! It's the end of a long weekend here!

 

Lol ok thnx ghost..
