I've thought about doing a Megasquirt for a while now to replace my carbs. I have a Mallory that works great, so to keep the initial cost down as well as keep it simple, I want to do fuel only, but have an upgrade path available for ignition later. Ideally if this could be done for under $500 that would be fantastic.
So... What is the easiest, cheapest, most simple solution for induction parts? Throttle bodies, injectors, TPS, etc...? Which MS unit has the flexibility to do fuel now and ignotion later without starting all over again with a different ECU? Engine is a 2056 that is built on a 1.8 case and heads with a 2.0 crank, rods and P/Cs. Currently running dual Weber 40 IDFs.

If it ain't D-Jet, it ain't MPS. (IMG:style_emoticons/default/wink.gif) Think of the MPS as a specialized MAP sensor built only for D-Jet. I've never heard of a MP sensor and would suspect that it's just another name for MAP sensors.
MicroSquirt/SDS/Motec/etc all use MAP sensors. MicroSquirt is compatible with MAF sensors as well which are a completely different sensors and are more accurate. |

(IMG:style_emoticons/default/laugh.gif) Another Q to no one in particular. I'm going to assume that all of the peeps that say MS1 doesn't need an MPS are now using some other sort of MAP sensor then? If so, what are you using and if not, why and how. Also, the same has been said of the TPS (you don't need it). Why? How? Thanks! This post has been edited by Gint: Jun 9 2009, 07:35 AM |

Hi Gint,, MegaSquirts have an on board MAP sensor (usually) so you can omit your stock one. The amount of vacuume an engine draws is directly proportional to the load on an engine, thus it is possible to run without a TPS. Having a TPS helps with some decel tuning and stuff to make some transitions smooth. If you do decide to build your own because of price,, think again because you need to also use a "jim-stim" to do some of the assembly steps. So the price of the jim-stim (which is a handy tool) should also be factored in to your costs. DIY or another MS vendor also sells wiring harnesses,, and one comes with the MicroSquirt, to offset the costs. I was always second guessing my own home built and that led to alot of wasted time. (Any MegaSquirt experts please drop me a PM,, I wanna hire you.) just my .02,, I hope some of it helps you. -Rob |

I can understand the ECU having the control circuit for MAP, but doesn't there need to be a sensor at the air inlet/plenum/etc...? As for the costs, I could pop for the full monty if I chose too. I'm not destitute. But I kinda want to do it cheaply at first to learn. In the end I'll probably spend a fortune. (IMG:style_emoticons/default/wink.gif) |
