BossHogg 0 Posted December 19, 2007 Ok i need a hand here, I currently have a 1.9 engine in my car thats running on carbs. it is using a distributer system, and i was looking to move to an OMEX 100or 150 management system, with also the idea of making the car a little future proof if i decide to go for a 16v engine running carbs as well. My questions are how easy are these to fit on a DIY basis, bearing in mind that i'm a mech eng who palms off electrical problems on a daily basis. (if it doesn't leak how on earth do you know where it's broken? ) How easy are these to map or am i going to need to find a specialist? thanks in advance Rob Share this post Link to post Share on other sites
Sandy 191 Posted December 19, 2007 It's pretty basic and you can base map it with your distributor advance values to get up and running. Well worth using mapped ignition, once it's properly set up, it's a world of difference. Share this post Link to post Share on other sites
mos 1 Posted December 19, 2007 would you not be better going for a full management ecu the money you can sell the carbs for would probably get you some throttle bodies that wil mount to your existing carb manidfold a full managment ecu is not that much more than ignition only. to get the most out of the ignition only ecu you will need it mapping properly, so you might as well have a mapping session for fueling as well. all in it will cost a bit more but take it from a man who has two 205's, one on carbs and dizzy and one on bodies and full management, once he mapping is right the differnece in mid range torque, general smoothness and even fuel economy is worth the extra effort mark Share this post Link to post Share on other sites

Miles 331 1 Cars Posted December 20, 2007 At last Mark, My way of thinking. I cannot see why people buy new carb's these day's But the ECU and looms come with instruction's, I'd get a semi terminated loom as you can cut the wires to suit instead of there pre made ones which rarely fit Share this post Link to post Share on other sites

Go for an ECU system that has the ability to fuel and ignition. Use it with the fuel system being redundant and just the ignition side working, then save up for throttle bodies and fit them at a later date. Sit back and enjoy smoother enginre running and still retain induction roar Share this post Link to post Share on other sites

Sit back and enjoy smoother enginre running and still retain induction roar yes the only thing to be wary of is depending on the mapper you use you dont want to pay to map the ignition only, then again to do the fuel at one of the places that seem to charge a flat rate for mapping regardless of how long it takes. find a mapper that charges you for the actual time taken so you dont take a double hit on mapping when you upgrade to bodies at a later date mark Share this post Link to post Share on other sites
matt-k 0 Posted December 22, 2007 Can i just add a quick question! I was going to invest in a megajolt mapped ignition for my carb engine at about £100, how much would an ecu like the one above mentioned cost me? Cheers, Matt. Share this post Link to post Share on other sites
BossHogg 0 Posted December 22, 2007 (edited) Can i just add a quick question! I was going to invest in a megajolt mapped ignition for my carb engine at about £100, how much would an ecu like the one above mentioned cost me? Cheers, Matt. Omex 600 series which is a full management system is about 550 quid, ignition only like the omex 200 series is around 350 quid. I initially looked at the megajolt idea, but i want to buy once and have the unit pretty much be able to do what ever i require in the future. Should that be throttle bodies and/ or a 16v engine. Thanks guys for your input. it's most appreciated Edited December 22, 2007 by BossHogg Share this post Link to post Share on other sites

Thanks guys for your input. it's most appreciated i am not sure how much the megasquirt (the full management version of the megajolt is) but as its a diy ecu its bound to be alot cheaper than the mainstream ecu's such as the omex etc. the one piece of advice i would give anyone going own this route is to do some research on mappers, who is good, bad etc. pm folks on here and other forums etc about who they recommend and choose the person who will be mapping it before buying anything. be prepared to travel to go to someone who is actually good and dont just choose someone because they local to you once you have selected a mapper ask them what system is there preference. whether it be megasquirt, omex, kms, dta or any of the other 15 or so ecu's that seem to be out there is circulation in the uk marketplace and stick to there advice. its take me a year to get my car spot on and now i am very happy with the result initially i took it somewhere that made a complete mess of mapping it. a place i later discovered privately on here where quite a few fellow forum members had also had bad experiences. but folks did not want to say in public but would willingly give you an honest opinion in a pm. my experiences are a classic case of "if i knew twelve months ago what i know now i would have had it sorted within a couple of weeks. " point is if i followed the above advice i wouldn't have taken so long to get a result i am happy with or cost anywhere near as much as my car was mapped more than once for various reasons. mark Share this post Link to post Share on other sites
