I have just had delivered my new 1400 MPI and been told i will need a new remapable ecu, has anyone else had this problem, can i continue runninig the original or if not has anyone got any suggestions which ecu i should go for?
cheers
What is the engine spec?
The only programable ECU that could work is CANEMS, if you are using the factory MPi manifold, there is no other option other than the dtandard factory ECU!!
I havnt recieved the specific specs yet, there being sent in the post with the invoice, I will post when they arrive. I have contacted canems for a quote on the advice of others on here but will this not work with the standard manifold? any1s advice would be appreciated as this could be a costly mistake
cheers
I have spoken to canems and been informed i need a crank sensor and tigger wheel, which iv sourced from KAD as a bolt on kit however they also said the standard injectors are only good for 90hp. which would be the best method to increase past 90, buying new injectors? or increasing the fuel pressure? or is there a better way? also the canems doesn’t support the temp senor, can i get a stand alone sensor and gauage?
sorry about all the questions
another ecu that you could use for an mpi is the icon superchip.. i dont know if its fully programable but i know you can load diffrent maps on to it for diffrent cars and im pretty sure it comes with a map for an mpi from what i have read before it should give you about another 5hp
ICON Race is an ignition only device, and for £300 I would want more than 5bhp and a slightly better drive. The fueling is the biggest problem.
Is it worth speaking to Dave Walker from Emerald?
it wont work with the factory manifold!!!
Going away from the factory manifold will get things working, mut when most think of MPi they think of the factory manifold
Apart from home brew is there any other option than the factory manifold?
if you decide to go the DTA route, I have an ecu available - very cheap.
I suspect your very cheap is not as cheap as people are thinking
> I suspect your very cheap is not as cheap as people are thinking
how about 50 quid? cheap enough?
cheers for all the help, I,ve now got my ECU, I have one last small problem, I need a stand alone temperature gauge as the ECU doesnt support the orignal, has anyone got any ideas where to get one from?
edited as the sensor is compatible, its only the guage which is not

Hi!
I just found this subject very interresting, as I’m looking to replace my rover ecu by the canems one.
I also have a modified Mpi engine (1340)
Would it be possible for you to explain me which parts are necessary to install the kit? It’s quite hard to find any informations or any subject about that installation.
Thanks
Aswel as the ECU, I’ve had to buy a crank sensor and trigger wheel, I chose to go with the full loom for ease of fitting as its a direct replacement and required no cutting into the original and then new 550cc injectors. I havnt finished fully installing it yet but the manual that comes with the ECU is quite indepth but easy to follow so no major problems so far.

That’s good news!
I hope to do the same soon!
I forgot to ask, which ECU have you chosen? is this the Canems? I’ve asking them a few questions about the ECU, but I didn’t get all the informations I needed yet.
If I can ask a few more things, which original sensors can you keep, and which one can’t work with the ECU and have to be replaced?
Thank you
its the Canems, I’m not fully up to speed so I may be wrong but as I understand it the only difference in terms of sensors between the Canems and the original is the temperature gauge, with the Canems, you will need a stand alone gauge rather than the orignal which is supported by the MEMs ECU.
Last time i read up on CANEMS was that it does not use the IACV stepper, so you have to fit the bulky noisey PWM valve to regain idle air control
im a complete amatuer and im not exactly sure what that is or understand the PWM reference, could you explain?
On the MPi Manifold there is a valve that contains a stepper motor. This controls the idle air, thus controlling the engine speed during cold start, warm up and when the engine is under load. The CANEMS does not have any stepper motor driving circuit, but has a PWM ( Pulse Width Modulation) output. In essence it does the same thing, but due to it using pulse width modulation, the valve is always on and as a result, generates noise.
You need to remove the original stepper motor valve and hash a PWM valve on there some how. Easy enough, with a bit of thought, but its just a bit more work, and for the life of me, cannot understand why CANEMS did not integrate a stepper motor driving circuit.
