im putting in my hondata soon and i was wondering if the hondata 2 step was any good? i heard both good and bad about it.am i better off going with the msd 2 step?if anyone is familiear with the system your input is needed.

 

I like my MSD better to tell you the truth. Its easier to change in a hurry at the track and you always know what it is by a quick glance to the pill box.

 

MSD is saffer because it cuts ignition not fuel

 

cutting spark can cause engine knock on the next engine rpm due to overfueling

 

well is that true about the hondata it cuts fuel. is that detrimental

But cutting fuel can cause ping, i would much much much rahter run it rich than lean. Also 2 step is hard on your car there is a reason you don't do it everywhere you go just on the line.

I have used my Hondata 2 step hundreds of times and it is fine. This is all false. Works like a charm. I do recommend you put a switch to turn this feature on and off. Helps with daily driving.

Works great for me also setting is easy. push a button, your engine light flashs, hold R's to desired RPM and step on brake pedal. Turn car off, back on and your ready to go!

 

how does the two step rpm not go on after the launch ie shifting to sec third fourth ect?

 

also what does the two step from hondata come with? switch, wiring or do i need more stuff?

Comes with the clutch switch. I recommend a simple on/off switch to wire in conjunction to turn it off when you aren't using it.

 

wht about the switch for the dash, the one to set the rpms?

works through hondata which reads vehicle speed. after you launch the clutch switch turns into a full throttle shift switch.

The dash switch to change rpm points comes with 3 step option also.

 

thaks alot man, i think im going to go with the hondata set up, also an off topic ?, i have the s200 with the boost option will it work on a non boosted car with just nitrous? ive heard yes and no?

 

dammit darren.....you dont listen to anything i say lol

I call BS. Explain mister. Overfueling is a rich mixture. Im pretty sure that I have never heard of a rich condition causing knock.

Now the drwback to cutting spark is a possible fouled plug and a F&F fire out the tailpipe. Trust me the Cat wont last very long either.

 

its a fact ask bubba from trackmasters (teamgendai) and he will tell you..having fuel left over on the next firing round can and will cause knock.now keep in mind..you do not run lean when you cut fuel..you have no fuel at all to burn so you cant cause damage cuz its not that it doesnt have enough fuel..its that it has none so there is nothing to burn.it would be like trying to start a car thats out of gas..no fuel no fire..no fire no burnt parts from ping/knock.

 

Knock is made by two seperate flame fronts colliding together. A lot of tuners will run extra rich to avoid and even eliminate knock in certain situations. Having fuel left over in a cylinder SHOULD not cause knock in a correctly tuned engine. It should be the opposite. The cyl walls will be drenched with fuel keeping any hot spots too cool to cause a secondary flame occcurance. If teh engine is prone to hot spots and/or has combustion chamber design that contributes to such problems I could see it at very high rpm. So in effect we are both right. Oh and you are absolutly right about the "no fuel no fire" 10million stock hondas cant be wrong I guess.

 

FULLTHROTTLE...I dont think most stock Honda driver sit at a red light bouncing off the rev limiter

Point being that most aftermarket units like the MSD or a engine management unit will cut spark not fuel...so the preffered method is cutting spark. Will cutting fuel cause knock and other issues...maybe? Keep in mind when the stock Honda ECU cuts fuel completely(At this time the throttle body is also closed) it is usually during decelleration when rolling down a hill or coming to a stop, but when it is bouncing off the rev limiter it is still cutting fuel until you drop below the rev limit...then it turns the fuel back on until you bump the limiter again and then it turns it off again...this coupled with the fact that your engine is spinning at 6 or 7 grand or more and the throttle body is wide open does'nt help the situation...see what i mean? I cant imagine it being OK for the motor? How about datalogging this event to see if it shows knock at all?

 

great insight from everyone, i thinkm im just gonna go with the hondata.
thanks

 

for the record, i have a UTEC (simiar to hondata but for subarus) and it has a launch control feature. i have mine set to ignition cut and my datalogs show that i get knock immediatley following my shift usually only the 1-2 shift, sometimes 2-3 shift. its fuel related and no big deal. usually a couple of counts and thats it. not to worry, you only do it (2step) a couple of times every once in a while.

you MUST use the spark cut for nitrous as well. never use fuel cut.
