4AGE ST20V Ke70 Razorback ECU and Loom running rough. Help!?

[Plelz]

Car - 1984 Ke70 sedan with 4age silvertop 20v

motor / part in question - Razorback ecu, loom and coils (four in one block, says GM on it).

problem - Engine starts but sounds like the timing/firing order is out. Backfiring, running on less than 4 cyls.

occurs/started when (if applicable)- ever since I have tried to run the engine, loom and ecu.

personal situation (if applicable)- I bought the engine, gearbox, Razorback ecu and loom from a bloke in Victoria. He said that it ran in his corolla when he pulled it out (can never be sure if this was actually the case). He said it had a rough tune on it for a st20v. Just trying to find out where my problem lies. Also, does anyone in SA know their way around 4age's with a Razorback loom. This thing has been idle for so long. Pretty keen to give someone some cash to get it running right/tuned so I can finally drive it. Help?

Gone from having a little bit of spark to none at all. Power is reaching the daewoo coils but none of the plugs are sparking. I'll invest in new coils and see what happens...

SO fuckin close to setting this thing on fire and buying a running silvia or something.

Buy adaptronic with a plug in patch harness or any other ecu that has laptop connectivity and go from there. Easiest thing to do.

Just been outside screwing around trying to get my car running with an aftermarket ecu. Having that digital dashboard and test functions makes it so easy to diagnose and figure out the problem.

If you really want to stick with the razorback thinger go and buy a benchtop oscilloscope and figure out where the signal is missing. The handheld ones aren't reliable enough. They only work sometimes.

^^ Best advice...

Anthony from kaizen can sort you out with a plug n play loom

Bought new daewoo coils. Plugged leads in and turned the key. Now it does not run at all. Just sneezes out of the throttle bodies and fires one cylinder when the key is turned to off.

Seems like an injector or timing issue. I want to see if I can get this working before I give in and buy a new set up.

Some of the prices I have been quoted for looms and ECUs makes me think I could go on gumtree and buy a running 4age ke70 for similar money. Frustrating.

Do you have spark at all ? And is the distributor in the right place ? Are the leads on the right order? Check everything before giving up on the ecu ay

If it's anything like my razorback loom check the connections plug on the cas or converted dizzy. Had similar problem and had wire loose

1342 firing order?
Check crank index position and correct firing sequence.
Is dizzy plug ok?
Does razorback need teeth removed from distributor like some wolf 3d ecu's?
Have you got a manual for it?
Called razorback?
