Just wondering if anyone had chipped their 335i. I see superchips are now selling the chip for the 335i for £600 iirc, I know CAA have a chip but it's mega expensive. I've got access to US products too so could do a SSTT or procede or DINAN chip. I do quite like the idea of a piggy back that I can easily remove for deeler visits but then I can see the advantage of getting it done properly especially including the warranty given by a decent tuner.

ANy thoughts or experiences from anyone over here.

I have an SSTT installed. It is the same unit as supplied through Superchips, but available direct from the US for almost half the price.

I like the easy and unintrusive nature of the install and the fact that it remains within stock parameters in terms of boost etc.

In terms of power, there is a nice improvement in power compared to stock, particularly low down in the rev range. People often say that the SSTT makes the car feel how it should have been stock (but people tend to say this with most good mods), but I expect that it is a very similar drive to the Alpina B3.

I expect my car to be putting out circa 360bhp - not up there with the Procede @ 400bhp, but nice non the less. I expect that I will upgrade to a Procede unit in time (V3 sounds like an excellent product) - probably once out of warrenty and when I have saved up some more dosh for a Quaife LSD.

All in all, I am well happy with the unit - an excellent upgrade for my manual 335i.

when you say stock parameters of boost? You confuse me. Stock boost is what 8psi!

to run 360bhp you will be running considerably more boost than stock, more liek 12-13psi.

Yahoo, where did you get the SSTT. I work offshore in the Gulf of Mexico near New orleans and have family here who could take delivery of the chip there. Did you have to specify the chip for a uk car or anything like that. And lastly how easy is it to install. Oh and economy apart from wanting to boot it more??

Thanks

The SSTT typically runs 3.3psi above stock - but is limited to aprox 11psi. Although stock runs at 8psi max, it can run up to circa 11psi stock depending on altitude. The chip intercepts signals coming from the TMAP sensor and adjusts them before being transmitted to the ECU making it run higher boost pressures. All other parameters for fuel, timing etc are handled by the stock ECU (including error handling), which for me gives me some peace of mind when compared to other chips which control these prameters directly.

The limitation of this approach are that higher than ultimate stock boost pressures can not be achieved (11psi as opposed to 15psi for the Procede) and therefore the effects of running additional mods (FMIC, DPs, CAI etc) are minimal, particularly compared to other chips which can run higher boost pressures in order to benefit from additional mods.

The benefits of this method are true plug and play functionality and the hassle free installation.

The installation its self is easy. Aprox 30 mins first time around until you figure out how to unplug the TMAP sensor (which can be quite awkward). After this though, the SSTT can be removed/fitted in 2-3 minutes.

Economy wise, I haven't really noticed any difference, it is probably very slightly better if anything. I can still get 30ish mpg on a tank full if I take it steady.

I bought the unit from Eurobahn (the official SSTT distributer), there website is: http://www.eurobahn.us/productsbymake/bmw.html. It cost aprox £320 delivered. There is no need to order a UK spec, they are all the same. Superchips just re-label the SSTT to sell in the UK for £600. Even the installation guide is the SSTT one.

I also have a BMC panel filter on mine which in reality gives very small gains. All told I expect my mods to give +40bhp, therefore pushing out 360bhp (bearing in mind most 335i's dyno at circa 320bhp stock).

Regardless of the numbers, my car is faster than most and will certainly give some far more exotic equipment a good run. I find it difficult to think of anything else which offers such a complete package in terms of looks, refinement, quality, pace, sensation and price. An all round cracking motor .

Mate i got JBX.. turned my 335i into a beast for 2 weeks 390-400bhp.. was not fitted properly and one of the connectors broke, so my car started playing up, i sent the piggy back and now just waiting for New JB3 to come out.. cost me under £300 for nearly 100bhp..

Got to agree with all said above...got an SSTT in my 335i auto and it's a really good upgrade, but I do like the idea of the Procede V3 in perhaps 6 months.
Bought mine from reseller on ebay.
Car was recently in with dealer to get turbo actuators replaced and I left the SSTT in place (although did consider this carefully)...quote from dealer when I picked the car back up was 'wow...that really flies' lol

Is the SSTT easy to install compared to procede, I watched the proceed install video and got very scared, I could cause some serious damage!

Its plug and play. Clip out TMAP, intercept the connect with SSTT..... plug back .. proceed V2 is all wire messy. V3 is going to be plug and play, but at 1,400$+ is it worth it?

[Finnie]

I think I'm going to get the SSTT, nice and easy to install and remove, cost effective given that I can buy it direct in USA and gives me enough of a power gain. Not wanting to stretch the engine too much either, 40hp will do fine, back to E46 M3 standard

ok sold SSTT it is!

Will order this week and blaupunkt tha275 amp with tweeters (as recommended by Gizze - still unsure of the part numbers i need for the l7 tweeters however) still scared to take off door panels tho!

Thanks!

Although V3 is plug and play (which is a huge improvement imo), you still have to gain access to the ECU and unplug adapters from the ECU harness. Installing the SSTT just requires opening the bonnet, unplugging the TMAP sensor and plugging the chip in - it couldn't be simpler.

You won't be disappointed.

As for unplugging the TMAP sensor, the SSTT is supplied with a guitar pick - not easy to use imo.

The best tool for unhooking the sensor is to use the end of a USB cable to lift the hook (just slide it under) and then just simply unplug.

BTW - I would recommend that you follow the instructions and put the ECU to sleep before install. I unplugged the battery for mine, which worked fine, but I have since learned that these events are logged by the ECU and could look a bit suspicious to a technician if this occurs regularly - particularly before visits to the dealer. Not enough to red flag your car, but perhaps enough to encourage a technician to look more closely at your stored logs/codes.

Thanks for the advice Pal!

another question - you don't have to answer did you tell your insurance company. Mine is BMW insurance and will be concerned about telling 'em

[Serjames]

I'm happy to install procede's if anyone is in the surrey/west london area...

dead easy and only takes about 30 mins.

How do you put the ECU to sleep then 15 mins no power?? Is this really needed??

I think it is more than 15 mins, more like 30 mins - can't remember to be honest.

It is necessary because otherwise the ECU logs that the TMAP sensor has been tampered with. Again, not enough to red flag your car, but enough to make a technician delve deeper into your ECU to look for any other irregularities.

Disconnecting the battery does the same thing, but the ECU logs the disconnect. However, the advantage of disconnecting the battery is that it seems to help with the ECU adaptation process - this is the general concensus any way.
