Default B204L 1996 ECU upgrade

Hi there

I own a 9000 CSE of 1996 with a engine B204L and 185 Hp

My car alredy as APC solenoid, a Intercooler and a APC gauge in the control panel.

I want to do an upgrade to my ECU. I was thinking is BSR, is there one better?

This is the information that i got from my car with tech 2 at a SAAB dealer

PN 4661260

Version 4662698

Engine B204L-9000 C3 VSS

I live in Portugal so I have to send my ECU to be upgraded, but I need my car every day because I live 80 KM from my work ( 160 per day). So I bought a ECU with the same PN - 4661260 to do the ECU upgrade.

But I have a problem, the ECU came from a car that is supossed to have a B204E engine (I check the car VIN).

But when I check SAAB EPC i notice that the PN 4661260 is only for B204L engine (like my engine). Here you have a printscreen of it http://smap.home.sapo.pt/saab/4661260.JPG

The part number for B204E engines from 1996-1998 with VSS is 4660841.

The Part Number on the SAAB label is 4661260 (on the used ECU that I bought)

I want to now even if the ECU is from a B204E is it possible to upgrade and put it on my B204L engine? because the ECU is an exchange part and maybe someone switch the outside box and the interior is from a B204E?

Is there a way of trying the ECU on my car without a tech2 machine, because my car as VSS (vehicule security system)? disconnecting the anti thief alarm?


please excuse my bad english, I'm portuguese

Best Regards

Probably the car you got the ECU from was "tuned" from 150 to 185hp with a B204L ECU.
My advice: sell those two hard to find 185hp ECUs to some LPT owner (they are very rare, only made for the Portuguese and Italian market) and tune a cheap and common 150hp ECU.

Thanks Stefano

I also thought that about the car I got the ECU from was "tuned" from 150 to 185hp.

But I have been told that to do a ECU upgrade to my car (B204L) it would have to be on a ECU with the same part number them mine and from the same type of engine.

I think the differences between B204L and B204E are this:

- APC solenoid (B204L as one; B204E doesn't have)
- ECU maps (B204L - 185 HP; B204E - 150E)
- APC gauge in control panel (B204L as one; B204E doesn't have)
- Intercooler (B204L as one; B204E doesn't have until 1996)

The turbo is the same - Garret T25

Is there any electronic difference between B204L and B204E ECU?
Is it possible to put a upgraded ECU from B204E (150 hp - after upgrade from bsr 227 hp) on a B204L?


Best Regards

I thought that all Trionic5 ECUs had the same hardware (well post 96 ones have a faster processor but they're still interchangeable), and, since the software just gets overwitten durig the tuning, sending one ECU or another for the tuning shouldn't make a difference.

To be sure, I'd directly email your tuner of choice. It's a legitimate question to ask, and bobody knows better then them.

I'm thinking in BSR.

Does anyone recommend another tunner???

Does anyone had bad experience with the engine after tunning with any tunner?

I would think any of the good tuners could take care of you, SQR, JSP, Nordic, Maptun, they all make good ecu tunes for good power!

This is the information from 4 tunners

http://www.sqr.se/trionic5.php?vol=2.0&mod=saab 9000
237 hk / 5639 rpm
345 nm / 3327 rpm

http://www.maptun.com/webshop/produc...18&listorder=9
Stage 1 - 225 Hp, 340 Nm

http://en.bsrab.se/products/t769/
Stage 1 - 227Hp, 346Nm

http://www.nordictuning.com/main.php...000&sub_page=1
Stage 1 - 210hp, 320Nm

SQR is the one with more power 237 hp

BSR is the one with more torque 346 Nm

Nordic is the one with less power 210 and torque 320 Nm

But I think there is no diference between all of them, the ECU maps probably are all the same (diferent Dyno, diferent values)

But I want to know if someone had a good/bad exprience with some tunner?


Best Regards

I'm asking if someone had a good/bad exprience with some tunner because I read this thread
http://www.93forum.com/viewtopic.php...91aa8a4b6#1466
where it's written "If you just want plug and play, check out Partsforsaabs the BSR programmer. You can tune and untune your ECU when you want. You must know that BSR does not support thier product if your car breaks due to power upgrades. I know because I was a victim . I currently have a Nordic stage 3+ ECU and have had no problems. You get what you pay for"

But the guy that wrote this now as a Stage 3, so is engine is more changed then a Stage 1 that I want, I think a Stage 1 is good and won't bring any problems.

As told before I'm thinking in BSR because I think they have more expirence then the others tunners (they mod ECU for a large number of cars), but I don't want to have any problem with my car.


Best Regards

Its not so much a case of "you get whatt you pay for" its more a case of "you get what you ask for"

some of the suppliers are "fixed off the shelf items" and some of the suppliers will tune in accordance with your needs
At around stage 1 spec your not going to risk your car, it will be "other components not the ECU that will cause problems i.e. hoses, plugs etc.."
The variance between tuners is most pronounced with how the early / mid range torque comes on,
some are quite hard with this = nice quick pick up and delivery = extra load on the clutch - gearbox
some hold back the delivery until the rpm rises = needs more gearchanging = light on the clutch / gearbox
you want to add
http://www.jakstollperformance.com/
http://www.saabflight.co.uk/
To your list, both these folks are more focussed towards "providing what you want versus what they have" solutions

Thanks Norman

Thats the answer I was looking for.

So in my case a Stage 1 won't do much arm on the clutch / gearbox because my engine is a B204L (185 Hp standart) and the clutch / gearbox are stronger than B204E clutch / gearbox.

My engine (B204L) is supposed to have 185 Hp and it's used in some 93 too. but the when BSR measured a B204L engine in a Saab 9-3 2.0T 185Hp T5 -->1999 (I'm using this values because they don't have values for my engine in a SAAB 9000) the values they got were 200 Hp as you can see here http://en.bsr.se/products/t59/ and here http://en.bsr.se/products/t59/chart/ so the Average power increase is 25Hp (14.9%).

So I will have a lite more power and torque without causing great problems to my car, I hope.


Best Regards

Also consider that your (our) 9000(s) has a larger and better intercooler than a 9-3
