Power Mod EMS for N/A tune - installed
 

I've had this EMS sitting at home for weeks while I wait for bolt on parts from RX7store. Got sick of waiting so decided to install . I have not done any tuning with it yet ( all the maps are set to 0 from factory) but can report that so far there are no issues with the way the car runs.
Install was very straightforward & looks pretty tidy to me.
Hoping to get some conservative MAPS from Rotormaster later today that will a least give me some performance gains to enjoy while I wait for the other parts.
Will dyno tune at that time .

Cost is cheaper than Interceptor x but more than E-manage Ultimate. This is the same EMS that Rotormaster use in thier supercharged car.


Edit - just added dyno done yesterday 30th Aug
Blue line is factory tune
Black line is Rotormaster mild tune which is minus 10% fuel at high RPM
Green line a map I played with leaning it out by 14% at high RPM
No tuning was done on the dyno as was getting flywheel installed & did not have time. Hope to tune with scanalyser myself then go back next week for a full tune
Notes :
first graph is in KW & shows AFRs second graph shows HP & Tourque
got a 7-8 hp gain at top end but needs some smoothing out of AFRs
could not go past 8300 rpm as speed limiter kicked in (185km/hr in 4th)
so could add another 5 or so hp

Before you slam my car as weak ass . This is a Dyno Dynamics which typically shows readings approx 15hp lower than the ones used in US. Taking that into consideration would give a peak around 190 by US figures.

Edit : 22/9/06 Dyno tuned chart added - see pg2 in thread for more detail

looks good. lets see some numbers! woot woot!

^ i second that

So does it intercept the signal, or alter it? Basically, with this, do you have to worry about LTFT?

remember the ric shaw unit? same thing

It can work either way . can control injectors directly or modify factory signal.

I'm told it is improved since "ric shaw" but not sure how .

Just been talking with Joe at Rotormaster . It seems there IS a conservative tune in there already.
Was not going to mention that the car feels stronger mid to high RPM range because I thought I must have imagined it ................... :Eyecrazy:

piggybacks are like, so last year ... :cwm27:

Been running this for a couple of weeks now & happy to report the car runs perfectly .
No issues with idle /AC etc . Have played with the tuning a little ( using info from other charts i've seen here ) and it is very easy to tune . Currently trying to get parts together to make the AFR readout work so I can tune "on the fly" .
I've read all the issues people seem to have with E manage & interceptor - this unit does not seem to have those issues - at least in N/A setup anyway.

what issues are we having with the ultimate and int-x?

are you saying there are no issues ?

I'm not saying anything - you said that you don't see the issues those using the Ultimate and int-x are having. I just wanted to know what you're referring to.

MM has his ultimate working flawlessly, and I know of many int-x users who are also up and running, and quite happy with the results.

where can i purchase the power mod from?

Heard of issues with idle & AC on the interceptor & the emanage seemed to be something that required a lot of mucking around to get right - thats all I was meaning . Was not trying to slam them- they obviously can be made to work well.

I sent an email to DNAmotorsport earlier today,and guess what, I have already gotten a reply :) These guys/girls seems to be very service minded, and told me it was possible to use their ECU in my European RX-8 :) The only thing left now is a dynochart....

Dyno added to first post

Do you have a permanent CEL with this, or in the future with FI will you be getting a permanent CEL?

In N/A form you only modify settings in open loop as there are no gains in clossed loop anyway . For Turbo you can trick the factory ecu to think you are in open loop at lower throttle settings. So - no cel

Brettus, have you fitted your agency pulley yet, ie was it installed for dyno run?

no - fitiing that tomorrow along with RB duct . Then back to the dyno for a tune next week or the following . Hope to be able to show a before & after all mods dyno then.

Looking forward to your opinions of the pulley when you install.

regards
Rexi

Have installed pulley & duct now . I can't really tell any diference :(
However -as a result of all my mods the car feels stronger for sure . Just did some rolling acceleration tests against my mates Toyota Soarer . Pre mods we were always neck & neck from about 45mph up to 100mph . Now I get about 3 car lengths on him . So - yes it is quicker .

get your scanalizyer yet..

the intake air temp drop as you get over 100 km is impressive.

beers :beer:
