Twinky Posted September 7, 2011 Author Report Share Posted September 7, 2011 Welp...... ECU ignition output if fubar..... Checked the output signal with a CRO and a noisy sine wave is coming out. It's meant to be a square wave running 70% on 30% off. Soo...... I'm pretty pissed off.... Will be looking for a new ECU now. Which means re wiring the whole f@$king lot....

SLO-030 Posted September 8, 2011 Report Share Posted September 8, 2011 Its the ECU at fault or input issue? Quote Link to comment Share on other sites More sharing options...
Twinky Posted September 8, 2011 Author Report Share Posted September 8, 2011 Well I've been stabbing around with a CRO and it seems as though the output waveform is only 1v p-p. I'm thinking the driver amp is at fault. Will be doing more stabbing, maybe I just need another amp and all will be good. Quote Link to comment Share on other sites More sharing options...
SLO-030 Posted September 8, 2011 Report Share Posted September 8, 2011 Hopefully you don't have to do too much re-wiring etc. Quote Link to comment Share on other sites More sharing options...
Twinky Posted September 9, 2011 Author Report Share Posted September 9, 2011 I HAAAVVVEEE SSPPPAAAAAAAAAAAARRRKKKKK!!!! YES! f@$kern finally.... It still won't start though..... I've double checked that the timing isn't 180 out so that part is good. Sounds like the timing is off though so maybe I have to tinker around with the ignition signal. Finally thoug I have progress!! 1 Quote Link to comment Share on other sites More sharing options...
ke70dave Posted September 9, 2011 Report Share Posted September 9, 2011 very nice mate. getting close. what was wrong with the ECU? (re ignition signal output) Quote Link to comment Share on other sites More sharing options...
Taz_Rx Posted September 9, 2011 Report Share Posted September 9, 2011 you'll have to set the start timing to 0 so you can dial in the 60°btdc. Once that's done it should start, unless you've got other issues like fuel. Do you have pressure in the rail? Quote Link to comment Share on other sites More sharing options...
Twinky Posted September 9, 2011 Author Report Share Posted September 9, 2011 Ok so what I have done is made a simple Transistor amplifier to the output of the ECU. The ignition signal was only around 1 volt and was not triggering the ignition module. I'm thinking that the amp is casuing the issue but I am unsure. I don't know if the Ignition module fires on the rising or falling edge of the square wave. Fuel pressure is at 42psi. I know that shit if firing up though (smoke comes out of the inlet after a bit of cranking :) )I just need to get my missus to crank the engine while I get on the timing light.

Twinky Posted October 21, 2011 Author Report Share Posted October 21, 2011 SHE LIIIIVVVVEEEEEEESSSSSSSS!!!!! Finally got to the dyno and in less than three hours she is sweet! Sounds beasting! Turn them speakers up! http://www.youtube.com/watch?v=E-bOctd3WB4 Dyno graph with no usefull information. Apart from KW & AFR The cold start is a bit iffy, in that you can start it just fine but it won't hold idle for about 30 seconds untill it warms up just that little bit. From there it runs great. Launch is a little bit flat but then it kicks in and really pulls you back in the seat at 2500 rpm onwards. I think that might have to do something with the extractors. To eliminate the cold start I'm going to hunt down an IAC motor and valve and jigg something up. Supposedly ford does something really simple. Apart from that I'll see is GM has something compatible with my Haltech. I know know why the E6 was not the greatest choice simply because the resolution is not good. It only does mixtures at 500rpm incriments. Load sense is fine but by rpm these is much to be desired. I'm soo extatic right now words can't describe it. It feels really good when you have worked on something for soo long and given counless hours, blood, sweat, tears and then to see the outcome is just spectacular. It has rekindled my passion for it, so much soo that I think it's time for some body work! Unfortunately my computer has been wiped of all information from my current build ie, pictures, videos. But I will shortly write up something about aftermarket EFI using the 4k EFI gear. Woot! Quote Link to comment Share on other sites More sharing options...
Spencer[RL] Posted October 21, 2011 Report Share Posted October 21, 2011 WOW last time I checked this thread you were doing the whole Carby Sc thing.. Sounds nice! What ecu you using? Quote Link to comment Share on other sites More sharing options...
Twinky Posted October 21, 2011 Author Report Share Posted October 21, 2011 (edited) It's an old school Haltech E6, fuel and ignition control. Unfortunately the Ignition output is dead on the ECU so the dizzy takes care of spark instead. It would be supercharged but I chose against it because I didn't have spark control and I didn't want to root around with the dizzy weights. So when I get a new ECU I'll slap the supercharger on. Piccies! A bit messy but it works. I need to make a new backing board and I'll neaten everything up. Damn those facet pumps are noisy!

SLO-030 Posted October 21, 2011 Report Share Posted October 21, 2011 Awesome man! Congrats with the success :dance: Giving me more motivation to get stuck into getting the EFI shit in the wagon :dance: Quote Link to comment Share on other sites More sharing options...
carbonboy Posted October 21, 2011 Report Share Posted October 21, 2011 The last time I read this, there were 'issues'. Now it's *BAM* all up & running, top work Twinky! :y: P.S - your wheel well looks like it could use some lovin'... :wink: Quote Link to comment Share on other sites More sharing options...
Twinky Posted October 22, 2011 Author Report Share Posted October 22, 2011 Yeah, I'll be looking at doing cosmetic stuff now. Slowly though..... I'm expecting my first daughter mid November so I won't have much time to do things. Hopefully mid next year I'll pick it all up again but I will be slowly doing things until then. It's getting there. Cheers guys! Quote Link to comment Share on other sites More sharing options...
