How Much Boost With E85?

[arrydjay]

Ok so on the topic of injectors, I just called a local ID dealer and they said that on E85 they would in fact recommend the sards because they have had issues with E85 eating away at the ID's. Anyone heard of this? Also what kind of dollars should I be paying for ID's and where should I get them from?

[SS8_Gohan]

who the hell was that? sounds like crazy talk... no, that's my brother 'crazy talk'

if that were true, a lot of people all over the world would be in the shit.

I got my ID's from T1 racing. You can get the base Bosch model, but i generally recommend people to get the real thing. They're not much, but a little bit more expensive now because the Europeans can't get their shit together

If you go the Link, you need the expansion loom thingy, it's got the digital input.

Sensors were $350'ish from memory - don't need the content readout. The loom cable Trent thought was very similar to a AC Delco (?) product, i never chased up on that, but you could possibly skip on that for a cheaper option.

I saw some second hand sensors going for like $50 USD, so you could def do it on the cheap. Don't think any has really tested the reliability of these items as they age. Prob best to call Holden and ask them are the content sensors listed as a 'consumable'. If you go a second hand one, you'd be wise to invest in a E% readout, all display it somehow.

Depending on the tuner, and how many setups they've done, you'll probably find that they can get away with 3 or so maps, but as Paul said they're not 'start from the beginning' maps anyway.

We're going to play around a bit with how the content sensor is all plumbed up, will report back with any findings.

Link $1650

MAP sensor $200 (if needed)

Sensor, loom and display $650 ish

Few fittings and lines for the sensor... $70 or so?

TOTAL before tube is

$2,570

Install plus tune = up to your tuner.

So anywhere upto $4,000 I'd say.

$4000 is a shit load of 98 fuel, I don't think its worth it unless you really want the extra power E85 gives.

[arrydjay]

Sorry anyone in Australia that would have them in stock?

The car isn't a daily, so I might just throw a haltech in and tune it on e85 and then when ive got more cash and if I can be bothered add the sensor and do the whole flex fuel setup.

[75coupe]

hmmm E85 and a second boot mounted fuel tank is a hell of alot cheaper than flex fuel setup me thinks...

Hell I dont use the back seat anymore with two fixed back seats anyways, theres space for an enlarged fuel tank right there....

[Hanaldo]

wow thats annoying... you definitely need another map sensor as well with the link... sucky

Yeh it's quite annoying. I honestly think Link would be smarter to include a 3 bar sensor or ideally a 4 bar sensor on all their boards, as the Haltech external sensors are a fair bit cheaper than the options that Link offer. I can understand that they are trying to keep the cost of the board down and then make the extra profit by selling external sensors, but in reality they are probably losing a lot of money to Haltech and other even cheaper brands.

i didn't get a Link map sensor, i just got my stuff from tuffcarparts, they made the adpaters for the ID1000's for my different mm sized fuel rail. MAP sensor was pretty cheap from memory, $50? i don't remember it being of any consequence really.

EDIT: just checked email, $110... prob could find it under $100 as this was a while back, dollar is better now.

How much are the Haltech map sensors?

Dont leave the car sitting for too long with E85 in the tank though (i mean like months at a time) as a mate doing FIFO work has issues with it everytime he lets his car sit for too long, put fresh fuel in and its like new..... Not sure if others have this problem or not?

About the same, I paid $100 for the 3 bar Haltech sensor. The 3 bar map sensor that Link offer is $140 going off Speedtech's prices.

Sounds like it's taking on water.

Daniel, I found the sensors on ebay for around $300 delivered, I'm fairly sure you can buy the readout and use its 5v output for fuel temp and more importantly, 5v output for ethanol percentage as a signal to most ecu's with a 0-5v input spare, am I correct?

1650 link g4 rrp

650 sensor and display

1000 tuning

if r34 add map sensor 170rrp

done.

knock off $300 or so for the readout as well... even cheaper

scotty, i don't believe the E% can be sent as a 0-5v signal... from what know (which admittedly is not much) the signal needs to be sent as a digital frequency

if you're talking about the E% readout screen... yes, that does some sort of conversion i do vaguely remember thinking about using the output from that to the ECU... but can't quite remember. I guess what you need to do is make or get something that changes the frequency to 0-5v on the cheap, just skip all the screen bit, and just do the conversion.

[Piggaz]

need to locate secondhand GM ethanol sensors & content displays somewhere to make it cheaper....

Second hand?

They're like $300. Why bother!

What is a digital frequency lol?

You could get a 0-5v readout definitely, if the sensor is digital then it will need a special interface to work with anything, if it is just designed to work with the display then this is probably the case, but if it is designed to be input to an ECU it should be analog.

[linkems]

gm flex fuel sensor outputs a square-wave voltage signal. The signal varies in both frequency (50-150hz) and pulse width for fuel temp. Either pull the sensor's signal up to 5v to the ecu's digital input, or connect it to a zeitronix content display which has two analog 0-5v outputs one for fuel temp one for e content.

Do most aftermarket ecus have frequency counters for digital inputs you can use?

No, but most will have a 0-5v input if you use the display's outputs.
