LSonE Posted July 7, 2021 Report Share Posted July 7, 2021 Can anyone please help with info on this link ecu ? Was told it was on a rover v8 at some stage.... Is it capable of running a LS1 engine? How are they tuned laptop? Thanks in advance- Aaron Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 7, 2021 Report Share Posted July 7, 2021 It is a G1 "LEMV5". Really need to see inside to see what type of triggerboard it has in it - these ecu's need a dedicated board to match the engine trigger, you cant change trigger settings via software. Not suitable for an LS as it only has 3 ign outputs, so typically only used on distributor V8's. It is PC tunable. Personally I wouldnt bother fitting one as a new install today, far enough for an existing install, but hard to justify spending time and money installing something so dated and limited.

Dion Obrien Posted August 18, 2021 Report Share Posted August 18, 2021 Hi I have this ecu now and are putting it on a standard early 350 chev with a dizzy. See attached photo. Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 18, 2021 Report Share Posted August 18, 2021 Ok, That has a reluctor sub-board in it. It will need a distributor with an 8 tooth wheel and a reluctor/VR/magnetic type sensor. Im pretty sure the GM HEI distributor has a 8 tooth reluctor inside so that might be an option - without the HEI module. Quote Link to comment Share on other sites More sharing options...

Can it run without it. And do have to use a narrow band or can I use a wide band any benefit. And yip I'm a typical kiwi trying to do it myself on a paperbag budget lol.

Adamw Posted August 19, 2021 Report Share Posted August 19, 2021 I think that ecu is actually an older V4 that has been updated to V5 firmware. The genuine V5 had another 4 pin plug at the tuning port end for connecting a wideband, yours doesnt appear to have that so I would say it is only capable of reading a narrowband. An O2 sensor is not needed. Quote Link to comment Share on other sites More sharing options...
