Here is some info on the TEG ECU as promised. This is for the pre 97 however the post 96 will be identical and will be available shortly


· Plug in replacement ECU for any Subaru Impreza 2.0T using the 4 plug 93-96
unit

· Retain all original sensors & timing references, to enable conversion back
to standard ECU to comply with Grp.N regs

· Provide FLASH based code storage for easy upgrade & FRAM based calibration
storage for rapid access.

· Provide extra connectors for ‘Add-On’ features, like diffs, dashboards,
shift lights, switches, etc

· Various levels of calibration security. From none, right up to full.

· Build in as much hardware extras as possible, to give the software room to
expand later.

· Make some features enabled only on purchase of the higher priced model.
Customer can upgrade later if they want, with no cost penalty.

FEATURES

· 3D Fuel pulse duration control, based on RPM & MAP

· 3D Ignition event angle control, based on RPM & MAP

· 2D Idle Speed Control, based on ECT

· 3D Ignition event angle retard, based on RPM & TPS (ALS only)

· 3D Fuel pulse event cut ratio, based on RPM & TPS (ALS only)

· 3D Ignition event cut ratio, based on RPM & TPS (ALS only)

· Dual set point fan control, based on ECT

· Water spray control, based on AIT & TPS

· Fuel Pump output

· Shift Light outputs

· Error Light output

· Dual RPM limits

· Ign retard based on AIT

· ‘Dual Base Maps’ i.e. FPD,IEA,WGSR,ALS

· Diff control is to be as current unit



This may all sound a bit technical if you're not into mapping engines, so
here's a few of my thoughts that would apply to road use.

The troublesome Airflow Meter is ditched. You can either leave it on, or
take it off, but the ECU pays no attention to it either way.

Each ECU will be custom mapped to whatever level the customer wants. We will
NOT be supplying maps 'via the post' as it where.

The price of £895 is for the base unit to be installed and mapped at our
premises. We do have a mapper who can come out to a customer, but the
customer will have to pay mileage etc.

The 'Base Unit' does not include ALS, Active Diff, Dual Maps, Shift Lights,
Water Injection. These are charged as extras because they involve either
extra parts or extra time to set them up. We haven't yet finalised prices
for these options, but it won't be a lot. Just enough to cover the cost of
the parts and some time to install them.

The standard Boost Sensor (MAP sensor) on the 92-96 cars is only suitable
for use up to 1.2bar Boost. If anyone wants to go past this, the ECU can
support it, but the customer will have to pay for an up rated sensor.

As i said before i cant wait for the my 98 one to become available

Thanks for that gossy

The 'mapper' quoted above is Steve Simpson who has been involved in the ecu's development. They currently have one on test in a Scooby this week .

Where did you get all that info from ?

gossythevaleter

from teg themselves as they now i am very interested in getting one i may speak to em about doin a group buy

The big question is... will this be (easily) user mappable?

MarkDob

Why would you want it to be easily 'User Mappable' ??

I for one, wouldn't want to be fiddleing around with the maps, as I understand that you can do serious damage to your engine if you get it wrong.

This new ECU has two maps in it which the user can select, so I can have one for the misses to drive it around with, and one for me !!

MarkDob - coz some people are interested in that ! that's why alot of people ARE interested in this product!

Gossy - as you seem to have made contact already - i wonder if you could ask this of them too. i.e. a 'supply hardware & mapping s/ware only' option ???

coz that would (i'm assuming , given the all in cost mapped etc) seriously contend with the LINK ecu.

is there any more technical information on how many load point etc there are in the ecu? (i.e. LINK's are 6rows, based on MAP - but are interpolated (sp?) to about 16,000 - but makes mapping a bit fiddly IMHO)

I have already asked the 'supply only' question and at the moment they are not prepared to do it. They haven't answered me yet on user remapable, but I would estimate they haven't quite got the software user friendly yet, or perhaps they are using someone elses like GEMS.

right-o , thanks for that Paul.
not sure i fully understand the GEMS bit , but i take it you mean they may not have the interface for it yet & have a work around

I spoke to TEG on Saturday (ordering suspension stuff) and mentioned the ECU. They said that the guy who designed it didn't want anyone mapping it themselves initially, but they were looking to review it after 12 months. I asked if the software wasn't quite ready for public consumption, and apparently that's all well sorted. I guess an ECU is too often judged by the quality of the maps you find on it, and they want to ensure it's seen in the right light?

gossythevaleter

Yer but the best bit is that these will be mapped for each individual car and what that person wants eg two maps say hi and lo boost etc

TEG Sport

Hi All,

I haven't been on here for a while, and hadn't realised there was quite a bit of 'mis-information' on here regarding the ECU.

As I designed it, hopefully I can straighten one or two things out .......

User Mapping :
Initially we have taken the decision NOT to allow either user mapping or 'supply only'. This is due to the fact the product is brand new and we want to ensure that we have control over the mapping. From our point of view (and yours) it would be a disaster if someone, through no fault of the ECU, caused damage to an engine. It would almost certainly get blamed on a 'crap ecu' which would do us no good at all ! We will be reviewing our position over this matter as time progresses.

I hope you understand the reasoning behind this decision.

Software:
I'm not sure what the reference to GEMS software is, but this ECU uses it's own software.

Release Date:
The first production batch are currently being manufactured. As soon as we have them and have tested them, they are ready for installation. The boards seen at the Autosport Show, are pre-production fully functional prototypes, which we have been using on a UK and Jap spec car.

Versions:
The first version we have available is for the 92-96 (4 yellow plugs) model. The 97-98 (3 yellow plugs) model will follow shortly after that. We have yet to make a decision on the version that will be done after that.

Hopefully this clears up one or two issues on this thread. If anyone has any other queries regarding this, please post here, and I will be happy to answer them.

Thanks

Andy

Price and delivery Stuart?!

Pavlo

screw that then!

in 12 months I will have a MoTeC thankyou

TopBanana

I don't remember any case of someone with a blown engine, on here at least, ever blaming the engine management system?

In my humble opinion, the key to selling lots of these units is getting them into the hands of the expert enthusiasts (like Pavlo) who advise countless numbers of others (like me!). I understand your concern, but I suspect it might be a little misplaced. It looks like a great product, and it could do very well indeed if you play it right. Just my $0.02

thanks Andy for your input & for setting a few things straight.
good work on the ECU !

completely agree with you on the 'supply only'. I can see where all your hard work could be trampled on if someone decided they could map it & ended up blowing their car up (like me )
hopefully, when the product is out there enough & has been tested to hell & back (which no doubt will be sooner than later!), you'll review the supply option. I'm sure there will be a large market for this too - as the link ecu has proved!

however - as jlanng has pointed out, there is a very strong market for the cheaper end of ecu replacements, and some people are more than capable of mapping. hopefully, you could do an aproved mapping scheme or something?

Steve

TopBanana

I don't see how, unless the ECU actually was at fault.

It hasn't done Motec, Link et al any harm has it?

Dark Blue Mark

You must appreciate their point of view though?

Its a pretty big product which will obviously have a lot invested in it... You can imagine a couple of people using them without a clue what they were doing, then coming on here spouting that the ECU wrecked their engine. Ive seen very similar posts some time back, and it all gets messy.

I agree that some of the ECU guru's on here would probably pick it up pretty quick, but if it was my product, id want it kept under wraps for a period of time.

Not that big a deal, surely.

Thanks for the recent few posts. Good to know that people broadly agree with our current position.

Believe me, we want as many of our ECUs to be sold as possible. As has been said, we just need some confidence and control over it to begin with.

What happens after that is currently being discussed. We will be monitoring the situation, and would welcome any thoughts / suggestions people have regarding it. Pavlo has kindly made some suggestions off thread, and these will be evaluated to see if we can accommodate them.

If anyone wants to know any further information, please ask. This isn't a sales pitch, just a way of ensuring that anyone who wants any info on it, gets the correct info !

Thanks

Andy

Pavlo

I have had some more info from Andy. And there are a few things which need to be tied up before public consumption anyway, they alone are reason enough to not give it to the great unwashed.

did anything ever come of this??
