Diagnosing a standard ecu

[Adam M]

Hi ukso

I can't find if my ecu is standard or not

Firstley what power can a standard ecu produce?

As my car defo feels 200 bhp if not more ( have no printout)

Secondley the ecu just has the standard sticker on it no aftermarket logo or stickers all i have are the codes which are these:

Toyota

89661-10200

211000-4290 12v

26p 16p

4e fte

P -

-

Reason is the tuner needs to know or shall i show him the ecu and see what he thinks

If anyone can shed light please do

Thanks

Adam

Open it up. Stock has a single board. Aftermarket has a secondary.

But be warned some ecu's are said to have a light sensing chip that goes blank I've opened (apparently)

Stock ecu revs to 7700

Speedlimiter at 112mph

Boost cut at 0.85 bar

Both the later can be removed with a speedo convertor and a Fcd

Thanks allot for the reply mate i'll have a look!

Mine is running about 11-12 psi so 0.85ish bar

Limits at like 8500

and does about 120-130 mph i think so must be aftermarket i guess

I'll check thanks for the info massive help!

With rpm that high I would assume so. But yeah if you open it up you will either see a board with a 2nd one on top a bit like this

That means it's non standard

Stock 4e-fte ECU revs to 7200 rpm.

Maybe a plug n play!

[morgey]

Stock 4e-fte ECU revs to 7200 rpm.

I stand corrected.

I don't have a 4e or 5e so

Stock 4e-fte ECU revs to 7200 rpm.

EP82 is 7200 and EP91 is 7500
