I'm looking some past "post" and realize that a lot of people are satisfied buy their piggyback, but some a disappointed...no eminent hp gain ...

My question...Did i have chance to broke something in my engine by putting this piggy in my car?...Did someone with an 05 RA manuel have already make that move?

I'm scared about cut wires...If the dealer see the cut wire, it could be a problem...
thanks FranK

 

The chance of them looking behind the glove box to see if you did anything to the ecu is very unlikely. Unless you have a mechanic that is just fixated on busting you with aftermarket stuff, you should be alright IMHO. My only reason I wont go with the piggy is the cost of using premium considering it doesnt add all that much power for the money. Just my two cents

 

just to add another suggestion for the piggy: why not make one optimized for 93 octane? i know CA is super gay and doesnt allow the sell of 91 octane, but the other states do sell it, and its hard to find 91 in most areas. its not hard to reflash these things. why not offer it optimized for 93 and 91 to make the other 90% of us happy?

 

Because it's time consuming and expensive to retune the software, and when you aren't moving all that many units in the first place, cost is a very big issue.

Just because you've got access to 93 octane doesn't mean that you need an ECU tuned for it. The benefit you'd see moving from a 91 to a 93 tune would probably be far from noticable. Not worth it to the manufacturers to reflash for 93, and not worth the extra cost that would be passed to the consumer.

 

I've no probs with my piggy. Proven 15 whp gain... have dynos to prove it.

Off topic: blk... what the situation with your car? I thought you wrecked it.

 

ErikT: Its getting fixed as we speak. I got a check from the Ins Co. Looking for OEM parts that are not new (IE: cheaper) from wrecks. If anyone knows of a wrecked RA /w a good rear end, lemme know

Anyway, I'm not talking about the lose of performance from using 93 as opposed to 91. Im talking about not taking advantave of the potential. and to reflash, it takes about 45 seconds....2 mins tops if u include walking to the PC, loading the software, importing the saved settings, plugging in the unit and applying the flash. i hardly consider that to be very time consuming, figuring RRM profits about $200 from every ECU sold. The only work involved would be a couple hours trial and error /w a wideband, at most. I dont see how thats very time consuming, or expensive. it is a performace product. why not try to get the BEST performance for the customer? that, or maybe offer the software and 93 flash for a small price. its just a suggestion.

 

The piggy was dyno-tuned, which is expensive. Then take into consideration that it's a low demand item, plus a business that doesn't move tons of product. They're forced to run big markups so they can afford the people that it takes to run the business. $200 profit off a ECU isn't that much when you're only selling a couple dozen per year.

To answer a question in the first post, the reason some complain about the power gains on the piggy is because they're only looking at the peak HP it gives you. The true beauty of the piggyback is what it does to your entire power curve, especially in the low end. A more even and overall powerful curve that is very noticable when driving.

 

if it was dyno tuned as you said, i been asking them for the first and last dyno graph to show the difference.. but they insist they don't have the dynos to post

so how can it be dyno tune?

we have 106 here in ct

 

right on the money.....

 

it wasnt dyno tuned and doesnt have to be. only reason u would want to dyno tune /w the piggy would to be to find the optimal air/fuel. I think we just assmed a ratio of 12-14 is ideal, but this hasnt been proven. so, to tune the piggy for a certain fuel, read the AFR (wideband, i hope) and tuen until its as close to a constant 12-14 reading as you can get.

if u know the correct ratio, u dont need a dyno. u just need a wideband. however, as others mentioned, i dont think anyone dynotuned specifically to find the best ratio for our cars yet.

bottom line: with 93, my air/fuels have always seemed a bit rich. if i lean out the RRM map a bit, im sure i could get some noticable gains to take advantage of my supply. instead of buying the map software for almost $100, ill prob just sell my RRM piggy and get an emanage or something to do the same and then some

 

There is a guy who is parting out a Ralliart right now on E-Bay; lives in Iowa, Wrecked the front end of the thing. You might want to shoot him an e-mail to see if there is anything you need.

I actually did have my piggy dyno-tuned, but I ended up resetting it. I didn't trust the guy doing the tuning. He seemd to be learning on the job.

 

it is true that you only need a wideband to tune the piggyback.. but there is one problem

there is only two ways to tune for all the throttle points and RPMs.. either install a wideband in the pipe (like the AEM UEGO) and drive around a lot, tune and hope you hit every point (pretty unpredictable, traffic, etc will affect this)

or strap the car on the dyno, and drive..

you get the same results..

dyno is really just a treadmill for cars, so you can run in place without being on the street (and possibly running out of street on a hard run)
