Default Haltech v ESL on 98 UK Turbo

Hi All,

I'm well underway with getting a 98 UK Turbo Impreza back on the road.

I'm now at the stage of debating over what management to get. I'm all about doing things once, by doing them right.

More to the point, I'm debating over putting a Haltech 1500 into the car (mapping is another issue as I'm based in NI).

Any opinions between the Haltech and ESL?

I'll be unlikely to go mad with power, but the newer ECU and it's features does intrigue. Perhaps digital dash etc.

Many Thanks,
Neil

why would there be a mapping issue, there's a few tuners as well as myself that will work with a haltech? But also why not consider a link ecu as you will have much more options for tuning people with that too.

My advice is always try and decide who will be tuning the car for you - speak to them and choose the ecu they recommend. It will be the ecu they believe they can get the best results with and that works out best for you in the long run.

ESL is a great choice for a standard car - when you get to the stage of running mafless/speed density that's where standalone units will have the advantage.

Regardless of standalone ECU choice - I'd still look at forking out the little extra for a good quality air temp sensor along with a CAN based lambda and potentially a bosch wideband knock sensor added into the mix as our fuel quality isn't always the greatest.

Thanks Peter. We just don't have a massive selection of options like GB. Funnily enough, I'm even closer to you than I was before.

I'm really seeing what people have experience of from a technical point of view. Then I will decide how to get it mapped.

Funnily enough, the Haltech comes with an IAT in it's package.
