CamB 48 Report post Posted April 8, 2009 (edited) 3) and tuning, decided to go with a piggyback ecu but is there anyone in the country that has experience in tuning bmw's? Can the piggyback control spark (retarding under boost)? Which city are you in? Edited April 8, 2009 by CamB Quote Share this post Link to post Share on other sites

Boost Junky 1 Report post Posted April 8, 2009 Most descent performance tuners should be able to tune your BMW.. My tuner said he will have no trouble but has to start from scratch with the LINK as there is no basemaps available for bimmers.. Luke Quote Share this post Link to post Share on other sites
tigermoth 0 Report post Posted April 8, 2009 in wgtn, ...Silver Fox...i take it urve had experience with hi velocity. how were they? being in wgtn, ive looked at "the chequed flag" and "speedtech" and altho they kno there sh*t, non of them have had experience with bmw's, mayb im just being a lil padantic about it.as for timing under boost, the piggyback ecu's ahve no prob altho no one can answer weither the VANOS can be adjusted with the piggyback ecu or will i still have to run it off the standard ecu Quote Share this post Link to post Share on other sites

CamB 48 Report post Posted April 8, 2009 If its piggyback why does it need to control vanos? Won't the existing computer still do it? Either way I think its only a switch on single vanos, so if the piggyback can do VTEC (etc) then it could do Vanos. Which piggyback are you thinking?

Either way I think its only a switch on single vanos, so if the piggyback can do VTEC (etc) then it could do Vanos. Which piggyback are you thinking? i want to adjust the vanos with the torque curve, try and do a run with vanos and then without and where the torgue curves cross is where the vanos should kik in. i dont kno if this is totally correct so feel free to rite me. ahvent decided on a particular piggyback ecu yet, still shoping around to see what ecu can do compared to X Y Z etc. Quote Share this post Link to post Share on other sites
Boost Junky 1 Report post Posted April 9, 2009 Have you looked at using MegaSquirt from the states? Im not very famliar with it but im sure its relatively cheaper than the next step up like Link or the likes.. Depends how much you are willing to spend.

Guest FrantiC Report post Posted April 10, 2009 Megasquirt is all DIY too.. And can be run piggyback or full fuel / spark control. I don't think it can be used to control valve timing though. Quote Share this post Link to post Share on other sites

Ah ok never really looked into megasquirt, would rather just go all out and purchase an aftermarket replacement ECU. Of course that gets a bit pricey but so worth it in the long run.

No name user 379 Report post Posted April 10, 2009 MAPECU.COM ive already tuned a bmw with it and putting one in my turbo m20 2.5 and another into my 318i, very easy to tune and does lots of other things like switchable tables,launch control,boost control, speedcut/boost cut, o2 control obd2,etc etc Quote Share this post Link to post Share on other sites

But yeah obviously m50 turbo > m20 turbo lol. Quote Share this post Link to post Share on other sites

Haha doesnt matter what motor you are running the tune is still vital m20 turbo setup will still be sikk Quote Share this post Link to post Share on other sites

FrantiC: how much hassel was the megasquirt install with wiring tuning etc. did it work with standard sensors and vanos? Yup sure am Rich, its a Link G3 not the plus version though. Frantics motor is the older M20 motor Rich, which did not come with Vanos. Edited April 12, 2009 by Boost Junky Quote Share this post Link to post Share on other sites

FrantiC: how much hassel was the megasquirt install with wiring tuning etc. did it work with standard sensors and vanos? I was just chimming in that Megasquirt doesnt do VANOS.. AFAIK. Haven't used or setup MS before, Just in the stage of buying parts for my turbo build which is a stroked m20. - Probably lead me to buying MS for tuning.

320guy 0 Report post Posted April 28, 2009 Megasquirt will do vanos. Well, basic m50 vanos anyway, not variable vanos. You just need to setup an output in megasquirt to switch with vanos solenoid on, and you can set that to turn on where ever you want, wether its a MAP based value or a RPM value. Megasquirt wont be any cheaper with the exchange rate the way it is anyway. Get a link or somthing local. Quote Share this post Link to post Share on other sites
