Re: EOI : ST162 Owners! Group Buy - MegaSquirt ECU

StuC - yeah I'm going to be doing all of them at the same time just about Very Happy

But I guess if anything because the 162 will be simpler then it'll most likely be the mule!

Dont suppose when/if making them you could tune mine up for 98 RON off the bat so i dont have to fiddle striaght away?

Well - hmmm - I'd really rather do it for the one straight petrol. Any other maps would have to be done either on road (ie not so thorough) or extra money spent on a dyno. If everyone is in agreeance then we could tune them all for 95 or 98 RON unleaded - I will contact everyone and get their feedback on this just in case it turns out everyone runs on premium anyway, or are willing to upgrade to running premium all the time to get some extra hp.

Also, whats the PC programme and link like?Can it run real-time graphing etc with a laptop?

As far as I have read the microprocessor uses on board flash memory that can be re-written in run-time and read in run-time. There are also programs available called MegaGraph and MegaSquirt Log Visual Viewer which interface with the MegaSquirt via serial cable to perform logging functions. I'm confident it can do real time logging/graphing via the serial cable link.

Does this mean it will allow a conversion from AFM to MAP and thus ditch the shitty vane?or act as a piggy-back with the vane? What are the tech differents with each.(ie what extra modules are needed for that)

The module that will run the AFM will be of my own making (this is why this will take a few months - lots of programming to do!) - as their is no module available thru the MS community that will directly interface with the Toyota AFM - also the series 1 and series 2 AFMs differ slightly (basically from 1988 onwards) so they will have to both be accounted for. I will modify the software (MegaTune) so that you may choose which system you want to use (MAP or MAF/AFM). Each board will be capable of both, although you will have to fiddle/install the supplied MAP sensor. It will by default run the AFM - and each persons ECU will be set to either series 1 or series 2 spec electronics (although again I will modify MegaTune to provide an option for you to change if for some crazy reason you change things around).

Can we upgrade to dissy-less coil yet or is that not an option atm.It mentions a module that they're working on on the site.

Dizzy-less ignition can be accomplished using the Ford EDIS-4 ignition system with dual coil packs (waste spark system). I can supply the info on how to do this as I will be doing exactly the same thing on my 5S-GTE. You will, however, have to install a 36-1 crank angle sensor on your car, and being E-W you might struggle for room on the RHS there Very Happy

There is alot more dicking around but I could easily modify your ECU to suit at a *later* date once I've finished w/- the base level one and got everyone else sorted! Yes it will be a possibility, but it is something I am doing separate to this 'exercise'.

By the way - come on people! We only need three more interested parties and we can get going, and the more the merrier!
