SAFC2 v Blitz Piggy Back ECU

[grinder]

Hiya fellow FC owners :Thumbsup!

its been a long time since i started a thread in the FC section - so i thought i would make this a good one

i have recently purchased a SAFC2 ( from here infact in the last day or so ) , and i already have a Blitz MFCS ( multi fuel computer system )

so the million dollar question ..

WHICH ONE SHOULD I FIT ??  :3Confused

the blitz is a nice and simple plug and play item - there is only 3 dails on the thing - down side is that no one in the UK has heard of them and what they do - and only about 2 people in the states use them

i have contacted the UK importer for blitz and they are stumped aswell

now the SAFC has a wider range of users so i assume i can ask all sorts of questions and get some good answers

the SAFC has the nice screen so you can see at real time what is going on ( knock , revs , etc.. ) - where the blitz doesnt have this abilty ( it has a red light if you are running lean - but my AF guage will tell me this )

i have no idea what the results of either will be as i havent test them ( the blitz is plug and play where the SAFC needs to be wired in )

so not sure they best approach for this

just wondering if you guys have any ideas

Cheers

( must stop buying toys for the FC !! :driving  LOL )

Grinder....why not get a stand alone ECU that way is easy to map the car toooo.....but anyway....back to the question....i think SAFC will be better as tuner will prob know how to use it........

Is like HKS FCON V RPO...they are good ECU but not many use them in here...

[grinder]

i know what you mean sam

but its the pure £££££££££££££ of a standalone that not good

im still tempted by the apexi ecu to be honest - you can get the FC wiring adaptor for something like 23.000 yen - which someone said is about £140 ( although not sure )

and i would assume that you dont need to mess around with the car wiring at that point

im not after mammoth BHP - just 200 at the wheels and i would be happy

i have been reading up about the Rtek chips - and they sound really cool - but they only support the S4 so far - although they reckon they will have a S5 version very soon

i have seen you around the rx7club.com site - they are a very strange bunch of people - but very clued up

      keep an eye on Ausrotary there\'s always plenty of Microtechs going cheap in the parts trader section. There not very expensive when you work out the exchange rate. Either map your self or let Pip play, probably not be much more than what you\'ve paid for the two that you\'ve got now.

so you reckon i can get a microtech for sub £100 ??

this has to be seen

[grinder]

something like this ??

think the mt4\'s fuel only Stu. But if you keep watching its suprising what you can pick up. My lt12 was under £400 delivered brand new unused unit and loom still in the original microtech box.
Kevin

[grinder]

are they they ones that you have to cut and wire into the loom

so the lt12 is the one to go for ?? or would the 8 do it ?

[kev-yorks]

You only need a 8 stu lt12 will fire six coils/injectors the lt8 does 4 of each. don\'t go for a mt8 as these can\'t be upgraded now the lt8 uses stock coils the ltx8 uses the bosch aftermarket ones. As regards wiring its apiece of pi$$ i dont mined coming over and helping out. You can have it in and fitted in half a day. Couple of things to watch for are make sure you get a loom with it even if its only the plug and a few inch of wire, the early ones could only be mapped with the hand set you want one thats set up for laptop mapping (sticker on the back), make sure its configured for a two rotor (most are) and the very latest ones are set up for wideband a/f you don\'t need this but it makes mapping even easier if doing it yourself.

Sorry to high jack guys....

Kev, how do you find mapping the microtech, is it user friendly?? I know not many people use these in the UK, where can you/do you go for advise on mapping, etc :xconfused ??

Cheers Rich

so it a nut shell - i need to look out for an LT8 ( not the LTX8 )

and some wiring

if thats the case - i will have a look round and see what i can find

found a handset for one :

LOL

[sadgoth]

the new microtechs are LT8s (replaced the LT8) and the LT10s (replaced the LTX8) I have an LT10s with the uprated Bosch ignitors and coils, wired it in myself no problems until I stupidly swapped the trailing and leading plug leads round and flooded the car repeatedly! Took the whole loom appart to track the fault, messed around with the mapping, etc, etc in the end sent it to Tim at RX Motors who diagnosed the error in about two minutes! DOH!!!!!

I got mine for a good price new, no Stu, not under £100!

Depends on what you are looking to do with the car though, really you need to up the boost & increase fuelling. It can be done with a fuel pressure regulator and a boost controller. I don\'t know how the stock ECU would react to that though.
