hi guys/girls...

i've done a search, but cant really see a resolution to my question... so i'm hoping one of you genius's could help me out...

the background:

i bought an S13 Silvia with an RB20DET already installed. now, when i bought this car i was under the impression that it had a R32 ECU which had been chipped by Dr Drift and had also been tuned.

so anyway, among a long list of other issues which needed to be fixed, one of them was the wiring... so when i was getting the car re-wired correctly, the guy mentioned to me that it wasn't an R32 ECU, but rather it was a Cefiro ECU and that it definetely was not tuned let alone chipped by Dr Drift...

my question:

after the research i've done, i've come to the conclusion that the cefiro ecu only has 1map for the fuel and one for the ignition, whereas the R32 ecu has 2maps for the fuel and 2 for the ignition... this is all well and good (interesting to know), but it doesnt really tell me if its safe for me to be driving the car on this ecu...

it drives perfectly normal, but obviously very rich because of the mods i've done and the fact that its not tuned...

so if anyone can give me a straight answer if driving it on this ecu will damage the engine or not, it would be greatly appreciated...

obviously, i will be finding a R32 ECU to replace it with and then get it tuned properly... BUT, in the meantime, can i drive it around on this ecu?

thanks

ash.

toffy: yeah, i know... it wont be driven (let alone driven hard) while its not tuned... my main concern was driving around from the workshop and home etc..

although, in saying this, its been driven around like this for a few months because i was told it had been chipped and tuned when i bought the car...

and the engine hasnt gone BANG.....YET...

grandmasterb: pretty sure that its not out of an A31... from what i've read, the coilpacks are different or something like that... and the splitfire ones cant just plug straight in... and considering i put splitfire coilpacks in this just recently and it went in fine, i'm assuming that its a normal r32 rb20...

although, in saying that, my mate who has an RB20 in his silvia has a 4 ribbed pulley for the powersteering belt, whereas mine is only 3 rib... but i was told that the 94 model rb20 has the 3 ribbed pulley...

ugh... its all so confusing...

thanks for the replies! :D

      High temp brake fluid?

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣

      Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?

      Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
