ECU advice for 3S-GTE - Drifting forum

topi · 20-01-2006, 18:11

Advice needed ECU wise for the 3S-GTE engine, with roughly 400bhp.

Running JE forged pistons, Trust TDO6 with external wastegate (1.4 bar), SARD 800cc injectors, Walbro fuel pump, 20thou oversize bore.

Need to find a programmable ECU for a decent price. Doesn't have to be the dogs danglies, but it has to do the job properly. Been told the Power FC will just about do, and is the cheapest option. What about the HKS Fcon V-pro, or lesser known options?

Buying 2nd hand isn't an issue, as long as I know what I need to buy. Obviously there needs to be somewhere in the UK capable of setting it up also.

Any ideas chaps?

VEMS!!

Best to speak with BenR or Phatbob! they will tell you everything u need to know plus more for free!!

Apexi is a cheapish solution and is pretty reliable and a lot of tuners know em...HKS Cons are a step above..more expensive and expensive to map!

ask the guru's!!

Ah yes VEMs, heard alot of good stuff about that. What is the price tag on that kinda stuff though?

www.adaptronic.co.uk

A guy in Huddersfield who is an aftermarket ecu installer and mapper has just fitted one to an Mr2 Turbo, as a plug in unit using all the original loom (except running map sensor) installed and mapped within one day..

Power FC will be more than enough feller, the Jap tuners have got some serious power out of the 3SGTE with the PFC and there are quite a few UK tuners who are competent in this ECU and the 3SGTE. Thor do mapping on the 3SGTE.

Nengun do the PFC for the Rev3 for £440 (Inc commander) delivered which is way cheap. www.nengun.com

Thanks a bunch

Contact ATS racing in the states, they'll do a rom tune for you for small enough money.

**Kenny** · 25-01-2006, 06:41

can't believe i missed this post.

i have a 2nd hand Power FC for 3S-GTE up for sale if you interested. but no commander. it's a replacement ecu and i have erased the last map. therefore just plug in and it will run on base map. what car is it for anyway?? has it got a FMIC or top mount charge-cooler?? i am looking for around £375.

topi · 25-01-2006, 15:49

How much can I get a commander for?

It's for a '95 MR2, the cooling problem is yet to be solved. It'll have an intercooler made to fit inside the boot, or somewhere a bit more radical eg. outside the car.

**Kenny** · 26-01-2006, 06:42

check out Thor Racing, they do mapping and stuff and it's kinda local to you aswell.

don't necessary need the commander, if you do want 1, you need the extention lead from the PFC to commander, since one is in the boot and one is inside the car. and i have that lead aswell and you can have it for free if i can find it.

Kenny, might be worth bashing your goods on the www.IMOC.co.uk and www.MR2OC.co.uk shouldnt have an issue selling it. The ECU will work on the ST205 GT4 and the Rev3 Mr2 turbo (unless you have a specially converted PFC for the older AFM 3SGTE)

Their tuning abilities leave alot to be desired - They just ramp the boost up as far as it can go to get more power, as a result you end up with 250bhp @ 98psi.

What sort of power are you shooting for? The ST205 charge cooler is actualy quite a good bit of kit and can be retrofitted to the MR2. You can even use the old IC as a rad for the charge cooler. Spearco / Gredddy side mounts are quite good and can be had under 400 now. Boot mount means you loose the boost but also air flow isnt great over the IC either.

thanks for the suggestion James. I had it fitted on my ST205 and it's actually came out of a SW20, therefore i have the extention lead aswell. i believe they don't do one for the afm ST185 only for map sensor. and the different between the celica and MR2 is only on the charger-cooler switch. in this case it's perfect for what Topi is a SW20.

the charger-cooler set up it's only good for like 300-350bhp on the ST205, will need a FMIC after that. what i do is run the CC constant and a TRD thermostat which open at a lower temp. and the car was that cold and never reach the working temp. it's pointed half way between normal and cold instead of at normal.

i may suggest Topi to run a bigger IC as James said and have a Tom's air duct. there's a lot of SW20 running over 600bhp in Japan. check out the Phoenix's Power Fukui SPL they had some awsome machines.

topi · 26-01-2006, 21:18

400bhp is the realistic target.

The current set up with a Blitz Access ecu and SAFC was set up by Thor. It made around 280bhp and they claimed the fuel pump was topped out. I have real doubts about their abilities tbh, so if anyone can reccomend a midlands based ECU tuner with a good reputation, let me know.

Charge cooling is indeed an option, but Greddy etc etc Intercoolers aren't. They are in my opinion, very over priced, considering what an 'un-known' company can produce for half the price. The main issue is where to put the damn thing. As you said, the flow to the IC stuffed into the side of the engine bay is pretty bad. Alot of people put them in the boot, with a scoop directing air into it. Another possible option is to have a long-thin IC running the length of the rear screen, (outside the car) with air directed to it somehow.

All ideas welcome. Thanks for the help.

Easily 400 FWBHP on the TD06

lol only 280?! I made 295bhp (it made that on accurate rollers and on more than one occasion) with nowt more than a filter, exhaust, DP and a boost upgrade to 1.2 bar - no mapping at all and just running stock ECU. Car ran like a dream

They really are that shit!

Egay feller, the Greddy's go for sum £400 now. They are good for 400bhp. Also there is Berk Technologies - Head over to the www.imoc.co.uk and www.mr2oc.co.uk and www.mr2oc.com to see whats on offer.

They still dont do bad for cooling, once the car is moving then it does see a fair old amount of airflow. Just sheild it from the downpipe to prevent soak.

I was in the process of making some side scoop extensions to heklp duct in more air - sold the MR2 before I finished it.

I honestly feel for your goals ST205 CC or Greddy is the way to go TMIC is just overkill and only really good for the drag machines.
