dj-jon-boi Posted May 17, 2013 Share Posted May 17, 2013 just got my toms tecs ecu in the post. Since fitting it it starts but runs real lumpy, it wont rev up or idle. is there something i have to do before fitting it? Quote Link to post Share on other sites
Amjad Posted May 17, 2013 Share Posted May 17, 2013 Fit it, let it idle for 20 mins, give it a few revs and let it idle. If it's stable then go for a gentle drive, if not then let it idle longer and repeat. When you drive it go gently through the gears off boost, then again with a little boost, and gradually increasing after having driven it for 10-20 minutes. It'll fully adjust after about 100 miles Quote Link to post Share on other sites
dj-jon-boi Posted May 18, 2013 Author Share Posted May 18, 2013 It doesn't idle tho mate. It will only run with the throttle open. As soon as you let go it cuts out. It doesn't rev up either.. I've left the battery disconnected over night. Will give it another go later on. Do you think I need to keep it running for a while how it Is? Quote Link to post Share on other sites
Amjad Posted May 18, 2013 Share Posted May 18, 2013 If it can be kept running without throttle then do that. Not sure if would be anything to do with TPS or anything if it can't run without throttle? All the P&P ECUs tend to have a wobbly idle when you first plug them in but haven't heard of this before Quote Link to post Share on other sites
StarletSr? Posted May 18, 2013 Share Posted May 18, 2013 That is odd my p&p idles at about 1.5k for 5 mins then its fine doesnt even move about is your king lead in good condition? Quote Link to post Share on other sites
dj-jon-boi Posted May 20, 2013 Author Share Posted May 20, 2013 Well it runs fine with the standard ecu plugged in so the king lead must be ok. Matey said that his was set up for running 1.2 bar. I've got pretty much the same mods so surely it should work fine from just plugging it in... He said there's some switches inside it that you can alter the a/f ratio. Don't really want to be opening it up if I don't have to.. Quote Link to post Share on other sites
Amjad Posted May 20, 2013 Share Posted May 20, 2013 That's something I've not heard of before; that it can be altered! Quote Link to post Share on other sites
micky boy Posted May 20, 2013 Share Posted May 20, 2013 (edited) There must be something wrong with the ecu And your mate is full of kakka poo poo theres no switches! Also it dont matter if it was mapped for 1.2bar it should still run! Have you tried opening the idle screw abit on top of the throttle body?

Addymk2 Posted May 20, 2013 Share Posted May 20, 2013 (edited) TomsTecs ECUs can be adjusted for AFR.At least the ones for the Altezza and MR2 can. Never seen one for an EP91! Aside from that it should run fine. EDIT: Are all the connections fine from your loom/on the ECU side of things? Any grit or shit got in there?

dj-jon-boi Posted May 20, 2013 Author Share Posted May 20, 2013 He's not my mate lol. I did try the idle screw, didn't make a difference.. The plugs seemed fine, ill have another look later but I don't think it's that. It came with an adapter harness which is the same plug but just g Gives u abit more length of wiring. Ill try it without the harness and see if that makes a difference. Not looking likely tho. Quote Link to post Share on other sites

I have just asked my old man as he had a TOMS Tecs ecu in his MR2 Turbo and you Sir are right the AFR's can be changed! So now ill go and sit in the corner and hold my head in shame lol Quote Link to post Share on other sites
Addymk2 Posted May 20, 2013 Share Posted May 20, 2013 (edited) If the bod you brought it off knows about the AFR screw, could he have just wound it right up? Flooding your engine instantly and causing the crappy start? On a side note, tell your dad thanks Micky! lol Edited May 20, 2013 by Addymk2 Quote Link to post Share on other sites
dj-jon-boi Posted May 20, 2013 Author Share Posted May 20, 2013 He just said it was set up for 1.2 bar and it may be over fuelling. Ill open it up and see what's inside later. Hope I haven't wasted 400 quid! Quote Link to post Share on other sites
dj-jon-boi Posted May 20, 2013 Author Share Posted May 20, 2013 Just fitted it without the harness and it works fine. Haven't been able to test drive it yet as my engine is smoking really bad once warmed up Just fitted it without the harness and it works fine.

akyakapotter Posted May 20, 2013 Share Posted May 20, 2013 When was the last time you drove it what colour is the smoke bud ? Quote Link to post Share on other sites
bailey Posted May 20, 2013 Share Posted May 20, 2013 Im glad you sorted it pal was more thsn confident it was good was running over 200brake on my GT with it. As for people aaying its not adjustable it is on the air fuel mixture. The toms tecs ecu is one of the only ecus that doesbt have seals on it as the cover is purposly removable.As i said on ebay inbox i would never set out to rip anyone off let alone another enthusiast and club member.

morgey Posted May 20, 2013 Share Posted May 20, 2013 Stock corolla gti's have an adjustable AFR screw, but its put on the bulkhead instead of being in the ecu. ;) Quote Link to post Share on other sites
dj-jon-boi Posted May 20, 2013 Author Share Posted May 20, 2013 Bailey, I replied to you bro. Thanks alot mate, glad it's working properly! Well, where do I start.. I had a glanza, rolled it then put my engine In my mates gt. It was alright apart from smoking abit and it idled high. I drove it for a bit and the smoking increased. I thought it was the stem seals so I changed them. Then to find that it was still smoking. I then went to the turbo, as the engine has had 3 turbos all together and it was showing the same symptoms as when they went. I have a hybrid which I rebuilt the other week and fitted back on yet to find it still smoking... Great. I did a compression test on it yesterday an the results came back 163 ish on 1, 3, and 4 and showed 155 on 2. Not a great difference, been told by an ex rally engine builder it's not enough to worry about... What do you guys think? The smoke is Bluey white, it's defo burning oil. Earlier when I had fitted the ecu it didn't smoke at all whilst it was cold then as it warmed up it started smoking quite a lot when I revved it then it started to smoke on idle. Then once it was at optimum temp I revved it and a shit load of smoke ploomed out! Really need this sorted. The ecu cured a lot of problems but not the smoking unfortunately I thought that some of the smoking would have been over fuelling as some of the smoke was black but I was wrong.

dj-jon-boi Posted May 21, 2013 Author Share Posted May 21, 2013 Anyone? Quote Link to post Share on other sites
StarletSr? Posted May 21, 2013 Share Posted May 21, 2013 Did you clean out the exhaust? if it was the turbo possibly theres oil still in the exhuast and it needs to be cleaned out? just an idea? Quote Link to post Share on other sites
dj-jon-boi Posted May 21, 2013 Author Share Posted May 21, 2013 Well when fitting the turbo back on I noticed oil residue on the inside of the exhaust mani, also on the plugs when I did the compression test. This rules out the turbo doesn't it? Quote Link to post Share on other sites
Addymk2 Posted May 21, 2013 Share Posted May 21, 2013 I'm baffled if the compression test has came back fine. You got an AFR gauge? (ECU related not oil) Quote Link to post Share on other sites
dj-jon-boi Posted May 21, 2013 Author Share Posted May 21, 2013 No I haven't mate. Did a compression test by putting some oil in each cylinder today and there wasn't hardly any difference there either so it's a strange one.. Quote Link to post Share on other sites
daniel_g Posted May 21, 2013 Share Posted May 21, 2013 Take the exhaust off and pour petrol down it a few times. Then take it for a fucking good blast up a motorway to get rid of the left over shit in the system. If youve ruled out, turbo, rings and stem seals then chances are its oil residue in the exhaust.
