1stly no im not just being a deauche thinking its a cheap easy way to get a couple more ponies. With the ITB setup i will be installing i will be using a gen 2 head and higher comp pistons (only about same comp as gen 3). Now funding for a standalone ecu along with install and tuning costs at the moment just isnt going to happen and that essentially is all thats really holding me back from installing. Now my reason fro asking if i can use a gen 2 ecu is because it doesnt require an AFM (will have to fit MAP sensor?) and will deal better with raised fueling and raised compression. Also i ask this because i know people have made a gen2 3SGE run on a gen1 ecu, so why not the other way round? Correct me if im wrong but if i get a gen 2 ecu and loom from that side of things i should be sweet my only issue should be the interior loom????
There are two issues using the 182 ECU on a 162 I think the reason the later ECU's can handle compression is simple - knock sensor The 182 has no T-VIS, the ACIS is purely vacumm controlled. I think you are taking a huge chance without the knock sensor and professional tuning. At least fit an AFR and exhaust temp gauge ITB's and bigger carbs can be notoriously difficult to get a good "spread" and most make the mistake of over-fuelling to improve pickup but pay the price in pistons and sleeves. Also don't make the mistake of removing T-VIS, it's well documented that it has a detrimental effect on mid range power - which is where road going cars live 99.99% of the time
There will be no tvis. firstly beacause its a gen 2 ge head and the acis is virtually a quad setup after a restrictive single tb so i see no issue there. the documented mid range loss is on tvis heads wich is due to there HUGELY over sized ports for n/a where as the gen 2 has much better shaped and more realistic port sizes. As for the knock sensor i was unaware they actually used on but once again dont see that being such an issue being a brand new bottom end. Also with fuelling its a stock map. it cant be that insane lol I guess what i need to know is will the ecu/ loom combo physically work
^^^^ :hehe ........... I gotta admit though, it will be interesting to see how/if it can be done opcorn
Effectively he's going from a 60mm TB to a 180mm TB Without the cams and mods to maximize flow I don't see it making more power. I did this years ago on a 1500cc Alfasud with revved to 10 000 by fitting 45 DCOE's on it - It was good from 6-10 000 but a PITA lower down (The airflow wasn't enough lower down to get accurate feulling) - but EFI is supposed to solve that problem Compression High compression is a bitch on the road - At 12/1 Im stuck to local trips only (towns don't have 98 ron) I have to prime the oil pump every time I start it Timing is retarded to prevent blowups Your project I think without ACIS the effect on torque will be the same Without the knock sensor heavy detonation will kill any motor in seconds - regardless of age
I wasnt arguing. you raised vakid points i simply gave my response. also you have made some wrong assumptions about my build being standard. after market valve springs, cams, adj cam gears, adj fpr, walbro pump, ported head and higher comp pistons. so there is definately mods to support more power. As i stated this is a cheap way to bed the setup in while savijg a couple more grand for the stand alone. as i already stated. Im not some dumb ass noob, you know what they say about assumptions
rev. -i would think rather than use the gen 2 loom you could use your gen 1 loom and swap/repin the plugs at the ecu. but youd have to look at the diagrams to see how much would work. (ill bet alot) with some creative wiring you could use some of the now dead wires and extend them and repin for whatever else you need. as an example youd have dead wires that ran the tvis you could use to wire in a knock sensor....isnt the gen 2 knock sensor located in the same spot as the little whoorah on the back of the gen 1 block? -this would save you the hassle of trying to match up the gen 2 harness to the engine fuse boxes. -it would be worth a look at a 182 harness and fuse boxes but my guess would be that more will work that you think. i doubt its a completely different/new system. seems to me like a 182 is for the most part a 162 with a newer style and some minor upgrades. ive been wrong before though. -also if you look on ebay sometimes you can find some of the old "black box" type systems to delete the afm for cheap. w/o going stand alone.
Jon that may be a possibillity. il look at the pin out diagrams but im gettin an mr2 loom for free so im safe either way. Youve lost me, woorah? lol trouble is we never got 182's here so gettin a loom or fuse box from them is some effort. Hadnt thought of the black box method. i wanna go stand alone coz well you simply canyt beat the tuning bu on top of that i wanna be able to run duel maps. street and track to try and make this setup atleast semi normal
the who-rah...a.k.a the thingamajiggy. left side back of the block. has a little nut/bolt thingamufucker screwed into it. its like a bolt that flares out has some holes in it and then has another bolt into the back of it. i swear the bgb shows it as a "knock sensor" but theres nothing attached to it. i think its where the gte's must have a real knock sensor....maybe?
+2 The GTE and later blocks have the knock sensor in the middle (#3) of the block. Instead of the drain there is an extra pipe going to the waterpump. I have the knock sensor fitted, is there a way to wire it into the gen1 GE ECU? The gen2 head is probably the best starting point for an experiment of this kind. There are plenty of these heads around with sidedraughts on them
