Greddy ecu and harness

[Manny01]

Won't start, was told with a boomslang harness/wiring loom would just plug in and run. Light is on ecu. Any help? Thanks!

A harness will work as long as the greddy loom is attached to it, if its just the harness u get u will still have to attach/splice in the greddy loom in the correct order to it, best take the ECU out and label every wire u need then splice it back in checking wires twice before u do, also check jumper switches are in the correct order before u do.

[Manny01]

I've got 2 looms, one is complete with connectors on each that is the boomslang one I presume. and one has connectors on one end and has been cut out the car and just wires at the other end, also got a map sensor and wiring for the greddy. But using a greddy ebc.

put some pics up mate

The one that is cut should be the greddy one and that needs to be spliced in to the boomslang one, the map sensor is used for the greedy ECU to read boost basically it has nothing to do with controlling boost.

I see now u have 2 greddy looms and one is harnessed in for an ep82, that should work if it wired right and jumper switches are in order.

[Manny01]

Sorry for being ignorant but what are jumper switches? The settings on the ecu?

[triple j]

There a few switches inside the ECU. What was that ecu last running in was it a starlet

[Manny01]

Yeah. Ep82 tdo4.

I should start right up then, check all the connections are good on the looms and plugs in tigh . Only other thing I could think of is plunging laptop in to ECU and reflaching it with new blank map.

Sorry. Just been informed you plug it in alongside the original standard ecu, hence the name piggyback! Duh! Sorry for being dopey. I've got a jam ecu so thought it would just plug in the same. I'll fish the original ecu out and try that. Thanks for all the help!

[akyakapotter]

Lol emanage and jam interesting combo

[Manny01]

Yeah, lol. Gonna get the original ecu now and try that.

[triple j]

Lol.

It runs! Goes well but will get a remap booked. I'm in the south west, any suggestions. I know there's one in plymouth.

There is a few in Plymouth I'm from Exeter and take the trip up to tuning developments for mapping

[Manny01]

What's the website and how much does a remap cost?

Ive heard a few good reviews for engine tuner in portsmouth
