Have a s2 n/a exige and would like some more torque/bhp lower down the range,now I know everyone will scream s/c it,my funds dont allow this yet.
So been looking for ecu upgrades,hanger do a gt5700 that takes inlet/exh mods into account ,looks interesting and wondered if anyone has any experience of this ? Also the EMU black ecu looks a good set up and maybe upgradable if I win the lottery and go S/C any info welcome …and no I dont want to change my car for a s/c
It’s a no brainer on an NA, Hanger 111 as you say or Lotus may even still do it. In the short term change the cams maybe, manifold and airbox. You’ll sell them all on or likely find second hand but yep lowering the cam change is a good mod nervertheless 
I fitted the Lotus revised (lower) can switch to my NA Exige as I did not like the surge on the cam change. It made the car much more progressive to drive on the track and wet roads. It was just a cam change so no real HP hike. The Lotus 220 supercharger came next which transformed the car. It’s all you ever really need on the road. Looking at the price of the kit now (Alan White sports cars) it’s very expensive, I think I paid half that. It works faultlessly.
The 2zz engine has been worked by Toyota and then Yamaha. Both know what they are doing. Mods to wring more out of it are likely to have limitations on drivability or life. Forced induction is the way to go (sorry John!). Why not check eBay for crashed Exige engines with the charger fitted? I have seen them in the past, lotus owners do have the habit of parking their cars in trees.
I have the sports eliseparts silencer and trd air box on already and its dropped on the cam change .Hanger 111 do a 5700 gt ecu tune that is supposed to release a bit more top and more mid range with the mods and was hoping someone could give feedback on this.Replacing the cams I dont want to do yet Jonny (read your build on the n/a…wow) not confident on opening the engine atm.Supercharging ,yep i wish I could .As i say for day to day the car is great just wish for a more lower/mid power,sometimes you dont feel like revving it balls off
Before my car was supercharged it had the Hanger 111 map. As well as smoothing out the cam change it did release a little more torque, but as per above the most significant thing is really the cam change point as that makes it much more progressive to drive on track.
looking on the web ,BOE seem to yield some good results from unlocking and tuning the ecu
BOE is $850 and you would need to send your ECU to the states to get it done.
Hangar 111 equivalent is here: http://www.hangar111.com/shop/lotus-2-eleven-performance-kits/117-exige-elise-111r-ecu-remap-5700-induction-exhaust-or-b-type.html That dyno plot was from my car.
I did noticed the Hanger 111 ecu mod i thought that the map shown had the full system to get this,did yours have the full exhaust system inc manifold? I agree the BOE is a pain to have to ship the ecu
Have you spoken to RRR about their programmable EMA black ECU yet?
I am sure you are aware that this set up have been used in the Lotus Cup cars and feed back has been good.
yep,been in touch RRR and they seem to be on the ball but the cost is almost double,may have to bite the bullet and go with them.
Also to be honest BOE ain’t the quickest at replying,and I am not sure if I would encounter import or duty on the BOE even though I would be shipping mine out to them and receiving mine back,not sure how to get round it.
Interesting that you mention the ‘black ECU’. That’s what I’m running in my car now. Was previously on an Emerald but this offered much more control. Running really sweetly now. Not sure I’d recommend it for a standard NA car though. Still think that a straight cam switch map or the H111 map is the way to go.
H111 didnt recommend it due to standard manifold,and the cam lower is on the car already.RRR mentioned 15bhp at the hubs and 20-25bhp mid range on the n/a,not much more on top end but more torque lower down the rev range which is what I would like,sometimes I dont want to be wringing the nuts off it(could be my age).They mentioned the EMU also could run a supercharger set up (if I win the lottery) at a later date.Also I suppose worth considering if I sell the car I can swap straight back to standard and sell the emu set up to recoup some funds.Who installed yours and set it up
If you already have the lower cam change point then I’d stick there. The chances that you will get anything like 15hp without exhausts and intake are negligible. Save the cash for track days instead.
Its strange that both BOE and RRR show r/r print outs of standard motors and they seem to get a good 10-15 through the rev range and at cam change they recover 25bhp and no dip,top end not much but its the lower/mid i am interested in
Suspect they get more at the cam change as they will be compared against cars that havent already had the cam change point lowered. Think Lotus probably put the cam change at non optimal point for those that like the kick when it changes, rather than a smoother curve.
With respect to BOE and RRR getting more through the range, then I’m sure there is a little bit to be had, but from personal experience I only saw those sort of gains with induction, manifold, sport cat and straight through exhaust back box.
You only need to look at what Lotus themselves did with the ‘S’. They added SC to take the car to 220 bhp initially. If there was really an easy 15 bhp gain just from a map they might not have done that, or would have gone bigger.
One other more controversial observation. If you are worried about the lower/mid end then you aren’t driving it right

LOL …or I am getting old
