I'm going to have to disagree at least in the T7 scenario. The ability to break down and reprogram a T7 ECU is no small feat and the companies that offer these reprogrammed ECU's have people on board with skills held by maybe 20 people worldwide. Ideally these cars should be recalibrated with every piece of hardware added which involves many many hours of tuning and dyno time. Unfortunately this is not readily available here in the US so we make do with generric programs designed with certain hardware in mind. These cars are extremely complex and the cost paid is not because of the nameplate. Compare prices of Saab performance parts with Audi or MB performance parts and you will be suprised how inexpensive these parts really are.

Im going to have to disagree as well.

ECU reprogramming is not easy task. Like Xaa was saying there's few people that know how to properly tune the 3 dimensional fuel maps of ECUs w/o causing severe damage to an engine.

These ECU upgrades that Maptun, Abbott, SQR, and other companies sell are basically plug and play so that the Average Joe could acquire it without spending more and more money having their car constantly tuned by a someone who knows the system.

The EFI system you have is great for people who know how to tune, and know what the best timing and fueling is for different RPMs, but limited people know this. The good thing is that with Maptun (I'm not sure about other companies), you can upgraded stages for only $100.

I´d like to see you make a good tuning for a T7 engine xaa! Bypassing the whole ECU and getting control over the DI, MAP, MAF, knock-sensors and so on without risking the driveability and reliability of your engine is no task I would recommend anyone without a solid education in engine dynamics!
My experience with ECU upgrades is nothing but good and I´m quite sure that the problem here is something else than the ECU. You may find the price high, but that would be nothing compared to running into knock on high boost due to some miscalculation...

Duh! My mistake! I meant 'theoriginalscion' sorry!

Back to the topic, have you tried contacting maptun right away? Complain about the dealer not wanting to help, and if they have some suggestions as to where to look for problems. Also, you could take your problems to a SAAB dealer. Tell them that the car overboosts (but put your original box in) and let them have a look at it. At least, they know what parts to check (although this may be a expensive solution...).

Hey, have you tried disconnecting the solenoid? I just thought that if your wastegate is a little stuck, this could happen. Plz try to disconnect the solenoid and go for a ride. If the boost level is more than halfway into the yellow area, you have trouble with base boost.

Did I read correctly that your car only has 16000 miles on it?!?

If so the solenoid should still be covered by the warranty, as would the dealer visit that Bollman suggested - could be the cheapest way to go, but make sure you put the stock ECU in.

hey this might not help your problem, but you should get an aftermarket direvert valve as i'm sure the stock ones can't handle the power...

Ok, A really good independant Saab mechanic said basically without a doubt I am hitting fuel cutoff, and that I should adjust base boost, and it SHOULD take care of this. He has some experience with maptun ECU's, apparently, and he knew after speaking to me on the phone for all of 1 minute.

I will be seeing him Friday, so he can go over the car and be sure that nothing else is wrong with any valves, solenoids, apc's, plugs, DI cassettes, or who knows what else. Hopefully I will be able to tell you all how sick this ECU is by saturday.

Jeez, this seems so simple now in retrospect, but I wonder why Maptun themselves couldn't figure this out. they said it was plugs or DI, I had a feeling that was not it! I even told them that my "saab friends" on the internet suggested the idea of base boost being wrong, and they said it was not likely. Yet a mechanic who never even saw my car and a bunch of people on the internet who have not peered under the hood either both came to about the same exact conclusion.... wastegate/base boost

like I said, after Friday, hopefully this turns from a problem with it not working into a problem with me trying to slow this car down!

Thanks everyone who tried to help, If I had more time this week i would have taken your suggestions and been fumbling about under the hood trying to adjust this myself...

Well at least we were able to offer some insight. Boosting that much on a Stage 1 is pretty odd though. Can't wait to hear more about it once everything is fixed.

Here's the latest in the neverending drama:

went to see a good mechanic who races Saabs. he said my car is fine, I maybe just need to adjust the base boost. We lengthened the wastegate rod a half turn, still hits fuel cut.

another half turn, fuel cut.

another half, fuel cut.

another half, fuel cut.

total turns, about 4 or 4 and a half, still hits fuel cut in sprot mode, but in normal mode seems to be about 1 out of 10 times it will hit fuel cut, so this seems driveable. We tested it on these country back roads, where it is 55 mph roads and nothing insight but farms and barns... hit about 120 in about a 1/4 mile strip of road. Car pulled like a freight train, it just pulls, and pulls, it was almost scary. Really need suspension upgrades, and brakes too!

So, i thought I was all set, i get on the highway to make the long trip home, I go to pass, and BAM! fuel cuts out real hard!

So the car will still cut fuel when already at speed (65+) and you give it some gas... but starting from zero it seems to be OK. And all this is with the base boost taken down about 4-5 PSI!!!!!!!

Any ideas what i should do here, anything else i could check? I am thinking this thing is going back ASAP and i am getting a refund. Then, next summer I will do Koni's and Eibachs, viggen rotors or something, and maybe after that look into Nordic or SQR...

This is strange. Any chance you can get hold of a good boost gauge to record at what boost it cuts off and if the boost seems to race? The valve may be sticking sometimes, it has happend to me and then the boost just goes straight up in the blue and cut off is imminent (I have manged to let go of the gas when I see it coming). I have managed to "fix" the valve for now, but I may have to change it. The changes you´ve made to base boost is only when the valve is closed, even if you´re base boost is too high, the valve should keep it below cut off (although the ability to avoid spikings may suffer).

i am doing all supporting mods first to my car, as i have the same car as u pretty much 2001 9-3se hot my suspension will be here next week, (eibach springs r great) brakes will be done next, intake mbc and boost gauge already in, turbo timer wired but needs to be re-wired, and i dont think i will get a maptun, due to the problems u r having.

does anyone know if the bsr ppc is compatible with an automatic transmission?

I think all the tuners have programs for auto trannies....

This is the first time I have heard of any problems with Maptun. And usually people SHOUT when they have a bad experience, and are quiter when there is a good one. So you'd think if there were others out there with maptun problems, We'd have heard about it by now. that's why i am so confused by this. I have only heard the best about maptun, and yet i am having a tough time getting this thing to work.

i have written a very long email to Maptun, to see if they can help, before I send my ECU back for a refund. It is really amazing, up until the point where it overboosts and hits fuel cut. I really would like to keep it, but only if it works properly and safely.

oh, you might consider SQR, too. i have been hearing scary stories about the PPC system frying people's ECU's and making them unusable. They can't even put their stock software back on it, they just get fried and without an ECU your car is not going anywhere.

What is this about the PPC? I have not heard anything like this and I'm curious what has happened? Mine installed just fine but I have not tried to put the stock program back. When installing you have to remove a few fuses...maybe this was not done or the wrong fuses were pulled. The pictures of the fuses included in the directions did not match the fuse box on my car so I had to double check to make sure I was pulling the right ones.
