ECU Remap for NA - 200hp - 144lbft - 5750 cam swap

The Oily Bits S2 Specific Topics

I previously had the Lotus Sport ECU with the 5750 cam change in my car, but having fitted the ITG and Quicksilver manifold I like many others was frustrated that I wasn’t seeing any hp and torque gains from the improved breathing. Infact if anything the car was starting to run lean.

But now there is a solution. Hangar 111 have developed a new ECU map to extract the more power (200hp) and more torque (144lbft) after fitting the ITG and the quicksilver manifold and exhaust. Obviously in order to do this they have also resolved the fueling. The map also features the 5750 cam change.

My car was used as the test bed for this new map and I’m delighted with it. The mid range is significantly improved, even over the Lotus Sport ECU. With the weight reductions that my car already had it now rivals the standard ‘S’ for power and torque to weight.

ECU Remap - GT-Spec200 for A or B Type ECU

Another new development is remaps for the older ‘A’ spec ECUs so if you have been looking for a cam change ECU but couldn’t bring yourself to fork out for a replacement ECU nows your chance.

Blatant plug for Hangar111 over, but I really am pleased

Cheers

Wow, this sounds excellent!

Does the car feel quicker then? I tend to ignore numbers and go by how it feels

3

Yes the car definitely feels quicker, especially in the mid range where the extra torque is a big bonus, and as with the Lotus Sport ECU the car pulls smoothly all the way through the revs, instead of the having the step as it comes on cam.

4

Sounds great.

I like numbers Any chance of a RR of it?

6

What revs is the 144lb’s ft at?

I’d love to see a std vs this comparison dyno sheet…

Do the curves look the same, but just making more power etc… This makes me excited!

7

I have access to a Dyno if you want to get some stats

8

That I’d like to see mate, will you keep me informed, will be getting mine done very soon with Greg & Marianne. Hanger 111 Rock!

9

I’ve got a before and after dyno plot. I’ll need to scan it in. I’ll try and post tonight.

10

Sounds great but but do you have to have the ITg and Quicksilver to make it worth while? This is going to work out at about �2k+ to get it working.

Obvioulsy cheaper than going the S/c route though.

11

Yes, exactly what I’m thinking, I don’t want a new exhaust but I have a PiperX VIS. Would it give a decent performance increase?

12

Me too. Got ITG with a larini and decat (which I assume would give similar results) so all I’d need is a decent set of pipes and a reflash???

13

So if you spend �1k on manifold, �300 on ITG and �460 on the remap you get an extra 10bhp?
Christ thats alot of buck per bang

How have you reduced weight btw?

Excellent post Will. Its about time this was avaliable. Should have been like that from the factory.

Boothy, you need to get peak numbers out of your head (200hp)…

Concentrate a bit more on the way it makes power…

If its 15-20hp+ throughout the rev range, you would notice that much more than 10hp at 8200 revs

16

Ok here are the dyno plots.

Larger version available here

The car was mapped in Germany hence the units. Find yourself an online conversion to get the hp and lbft.

Note the standard curve is for the car with the ITG and the 4-2-1 manifold fitted. Not for a standard car.

I’ll try and answer some of the other questions above tomorrow, but off for a few beers now

The graph is nice but imho �2000 is alot of dosh for what is not really a big increase. Fair play to Komotec for giving NA owners the option to stop the ecu learning and killing off their mods but needing the 4-2-1 is a bit of PITA.

From other remaps on Toyota cars with this engine Im sure you can get a bit better midrange. The trick is to use the VVT correctly. Just changing cam switch point and playing with timing and fuelling will not get you the best possible out of the engine. Tuning the VVT takes considerable time but the results are worth it. Also the exhaust makes a huge difference.

You can get more than 200bhp with a decent manifold and free flow exahaust and a remap. In Japan Toyota used to sell the Celica TRD M with 200bhp from the factory quite a few years ago. All it had extra over the standard engine was a TRD manifold (same a standard manifold but with larger pipes)and a sports air filter and muffler.

Just to clarify that this is not a copy of the Lotus 5750 ECU with the learning disabled. It is a brand new map optimised for the better breathing of the ITG Maxogen and Quicksilver 4,2,1 manifold and sport cat. It still has the learn enabled. It also has a slightly higher rev limit of 8500.

On my car I’m seeing 201 hp and 145 lbft.

Dyno chart now on Hangar111 site here

The car currently weights about 865kg (Forged wheels, carbons seats, lightweight exhaust system, dry cell battery)
This gives a power to weight of 232hp/ton and torque of 168lbft/ton.

This is almost exactly the same as a standard ‘S’ 935kg, 218hp, 158lbft, giving 233hp/ton and 170lbft/ton.

Price wise I think its pretty competative. Especially at the introductory price. I was quoted more than that at Autosport to remap either my Mondeo or Seat. Both of which have larger markets.

If you’ve got a ‘B’ spec ECU its basically the same price as the Lotus Sport map, but gives more power from the aftermarket mods. If you have the ‘A’ spec ECU its cheaper than going down the Lotus route.

If you just want the cam change, without the remap then you can save for both ‘A’ and ‘B’ spec.

I can’t comment on how the map will work with other aftermaket induction or exhausts as I haven’t had those on my car and on track and on the dyno.

As for whether it is possible to get more power with more time and money being spent on it. I’m sure it is, but the time and money has to come from somewhere. I suspect that time would need to be spend working on different exhaust configurations with different maps till you find that little bit extra. We were starting with the exhaust as a given and then getting the best map for that. If anyone would like to step forward with something else then I’d be delighted to hear about it.

BTW: If you are contacting Hanger111 please mention that you saw my post and I might get a beer out of it.
