help s2000 not vtecing urgent!!

hey guys issue is as stated i thought id ask other s2000 owners as you might of run into this issue yourself

1. i recently turboed my s2000 with a full greddy kit and emanage ultimate
2. went to take it to get tuned and the car was not reving past 5.5k so we turned vtec off and the it wouldnt rev past 7k.
3. did a bit of searching around and found out a vtm wire was missing on my PnP Harness and had that wired up the car would rev to 9k no dramas.
4. turned vtec back on and same issue is happening again just bounces at 5.5k like there was a rev limiter on there. Movt bounce off that limited the vtec engagement point and where ever it went it would happen again jus
5.rechecked all the wiring and the wiring was sweet, stumped removed the turbo kit and same issue still happening.

Someone please help me!!!!

have u checked the parameters in the ecu's tune, possible the base map has limiters, and vtec disabled???

just a thought...................

yeah no rev limiter man

Unfortunately I know dick all about Greddy units.

If it isn't tuned yet, maybe a limp mode to get it to the tuner?

Hi Flipstar,

I have the Greddy kit although quite heavily modded now. We had similar issues to you, car would hit Vtec and lose considerable power. This happened with both the emanage ULTand the AEM EMS. Problem was solved by raising vtec enagagement to 7200 or 7400 (cant remember). Had something to do with the harmonics of vtec enagement with a log manifold.

So the car is still acting the same although back to stock with the stock ecu and stock injectors? Weird, maybe your vtec soleniod is stuffed?
Good luck

I know this sounds pretty darn stupid.
But change ECU.

Get something made for a honda. And youll have no troubles and most definately more power with compromising reliability.

i dont know who tunes the e-manage up in syd but Trent at STATUS TUNING ( http://www.statustuning.com/ ) in melbourne is a wonder with them. give him a call and see what he has to say?

have you had the laptop plugged in and been watching the maps and various sensors while it cuts out at 5500?
i dont know whats included with the GReddy turbo kit but it could possibly, tho i think highly unlikely, that PART of the problem may be a sensor is reading outside of the OEM range or there is a section of the map that needs to be looked at in more depth (ignition map including) that is causing fuel or spark cut

^^ yeah man trent is a good friend of 1 of my mates when he came up to sydney he put a pre tune on my car so i could drive it around i was very impressed with what he was able to do with the amount of time he has i will get him to look over it again when he comes up again:D

TODA here in sydney might be able to help..

The emanage ultimate is on their list of ecu's they have experience with.

Mine was purchased from the US. Im pretty sure it isnt the ULT as we had the same thing happen with an AEM EMS. The log manifold, small turbo and small downpipe is quite restrictive, bring the car to a competent tuner and lift vtec engagement to around 7400rpms.

You came to us with your problem....
A problem you created & were party too... Not the other way around...
When you have someone else strap together a complete pile of shit that only pushes 125kw at the wheels. (Not 150+ you're dreaming)
You have a real hide blaming someone else for your issues.
We explained your problem to you...
That is your cat/exhaust is ****ed & your emanage is locked.
We offered you a fix, but you didn't want that...
You prefered to leave it the way it is...
& like arseholes we charged you $50 for wasting an hour & a half of our time.
-1 rep point for you.

All I'm reading is excuses about a problem that originated from the owner.

Having a cry about a problem you created, and then are not willing to have fixed properly.........not cool...

Guys, tuners and workshops are able to provide solutions based on work they have done or will do on a car. It is extremely hard for someone to sove a problem on on work that hasnt been done by them. Alot of corners can be cut on even the simplest of modifications as I have come to find out first hand. Tuners can get you out of a hole most of the time depending on how big the issue is, and most of the time will have a fix even if it isnt the prettiest or most financially viable.

I was the previous owner of this car and i took it to TODA stock. I gave them a budget and the gave me a solution. With the standard ECU and naturally aspirated motor, it made 153kw atw after they had finished - on their dyno....Sometimes issues can be deeper than ther obvious and its best to stick to proven and tested solutions. If you do have problems, research until your fingers bleed as even one other poor soul on this planet will the same problem and most likely overcome them.

Yo Flipstar give us a call man. I might have a few contacts who can sus the car out for you dude. Its not the end of the cars life...eventually we'll find a fix mate.

You can make all the excuses you want as to why it doesnt run well, but NO workshop can probably save the current problems you have seeing the only person you have to blame is yourself or whoever put your car together, do you expect it to run well after strapping a kit to it and then plugging in a emanage without it being tuned properly, the amount of differences between how the emanage has been set and what you have put together could be massive, injector size, fuel pressure, octane of fuel, boost levels, intake temps, suitable map sensor all many varibles that could be giving you grief.

Why dont you go back to the installer of the kit, and if you bought the emanage why dont you have the code? The ability for an ecu to be coded is so that the tuner can protect his time and work that he has put into a tune, and if you dont have the code, then starting from scratch is your only solution if the fault is within the tune.

Also time is money, if you go there, and dont like the soloution they present knowing they actually have a clue unlike you do on the situation, then why shouldnt you be charged for thier time, if workshops didnt charge for the time wasters day in day out, they'd all be doing it alot tougher then they already are.

Also, how were they to know exactly what was wrong with the car when you ring up and say something along the lines of, my turbo s2k does hit Vtec, there mechanics, not magicians.

Let us all know how you go at the next workshop you take it to.

Why vtec may not be engaging is because, when you reset the ecu it has to re-calibrate the sensors & also see if you can run the emanage on a disabled mode so it by passes and runs off the stock ecu for now till you get it tuned.

WAN33Y mate for 50 bucks you got an hour and a half treatment... so id take the information Toda gave you and work towards a solution, 50 bucks mate you should be laughing...

they are all right man no point in flaming toda because they couldnt fix your car straight away everything takes time and you need to trouble shoot things yourself as well why dont you pop off one side of the intercooler and see if the car vtecs then if that dont happen why dont you check your wiring more then likely its a vtm wire missing in your
PnP harness that is the vtec oil pressre sensor sort that out then go from there it could also be your map sensor, my kit was spiking past 12psi and the stock map sensor can only take something like 10psi i heard. just research man thats all you can do ay ask people get opinions and ideas dont flame toda for pointing you in the right direction

For those with the Greddy kit, go to s2ki and ask politely for a unlocked basemap in the forced induction section. Plenty of guys have it there. I would help but I am on AEM EMS.Then go to your tuner and load the unlocked basemap and have them findle with vtec engagement, the stock exhaust is very restrictive but you should still be able to get good gains with vtec raised higher. TO get the potential of the kit you HAVE to whack on a free flowing exhaust or at least get a High Flow Cat and up the boost. 10psi was quite safe. I went up to 14psi eventually on stock compression but that was with E85, exhaust, high flow cat, boost controller, 750cc injectors. AEM EMS, GM 2 bar map sensor and a very good tune.

All want is for you to put more money into the car without actually fixing the problem. They want me to go spen $$$ on exhaust, which will not fix the problem. I told them exact issue i was having and they go they can tune and fix it. The tuner even wanted to wipe out my emanage and start from scratch. I go to him will it be fix. He goes i don't know. I go how am i going to drive the car if it doesn't get fixed. Its all about the $$$ for them. Find a good tuner guys if want to have good and reliable results. Those guys don't know how to tune and their dyno sucks.

If it has an unlock code and it is set by the original tuner of that map, then how the hell so you expect someone else to know the code? Go through each number combination one by one?

i wouldnt go slagging toda/ adrian and his workmanship, if u do some research in boosting any car especially a honda, there is no way u can make any sorts of power with a stock exhaust, u need a minimum of 3inch all the way through with a good highflow cat..................

adrian is very well known and has done some amazing work, wether it be NA honda's or boosted honda's.

now ur e-manage is locked (from another tuner) or factory coded, so before u go blaming a tuner for not being able to unlock it, think about it logically, .... do u think u would be able to get into my laptop without the password??? its the same deal.

ohh well, hopefully u think about what u want to do and maybe ask around about what u want from ur car and speak to people who have done it before, .... especially before u go around thinking u know what is right and what u want even though u have no idea.....


no hard feelings, just frustrating seing someone slagging a very well known person and performance shop.... ;)

Lol, ever heard of a happy dyno? 144.6 stock shietttt thats heaps. No wonder their customers leave there happy.

to get your unlock code email greddy support with your serial number on your EMU unit they should send it out to you

i dynod mine it pulled 129rwkw stock

THROW YOU EMANAGE ITS GARBAGE!

you want to turbo ur car? dont use emanage
its a piggy back and your engine wont last for 1 year ;)

i learnt my mistake!

emanage is good for MIDLY moded car
force inductions change alot of parameter values on sensors and tune, not recomended.

GOOD LUCK FINDING ur problem

How do you know if the car made 150+kw atrw???? Why would you talk shit about Toda's dyno? I'm pretty sure that there are heaps of people getting work done and tuned there and pretty happy since Toda does 98% Honda.

Face it, dump the shitty greddy e-manage and its preloaded shitty map, get exhaust upgrade and perhaps map/maf sensor, injectors etc. And get REAL EMS!!! or at least AEm F/IC

Lot's of research buddy

FYI, running 6.5 PSI my car dynoed 182.6kw atw after being tuned.
